[QUOTE=CRGreathouse;475501]Rediscovery is commonplace, and not a problem. All of us have rediscovered existing theorems, algorithms, or the like at some point. The trouble in your case isn’t that you rediscovered Fermat’s test, but that you claimed that it was a primality test (no exceptions) rather than a probableprime test.[/QUOTE]
Hi CRGreathouse I had a look at the post by ewmayer again after the tread was reopened. For me they are similar but not the same...big difference. I think ewmayer might unwittingly have slightly tweaked my algorithm as posted. I would think that a simle and difinitive way to confirm the equivalance or otherwise would be to substitute values into the formulas...if the give the same exact result...they are the same....if they give different results, the formulas/algorithms are different. I claimed that the algorthm I had posted determines [I]primality and compositeness[/I] (albeit with false positives which is not unique with primality algorithms), [I]not[/I] that it was a pseudoprime/false prime test. [B]ewmayer[/B] suggested that "my" algorithm might or is likely a copy of an existing pseudoprime checker (which I am willing to accept), but simple substitution with values does not support the statement that the two algorithms are the same. Regards 
[QUOTE=gophne;475526]I think ewmayer might unwittingly have slightly tweaked my algorithm as posted.[/QUOTE]
No difference. It was a simple symbolic algebra reduction which you should have been taught in high school. If you weren't, that's your problem, not ours.

Hi CRGreathouse I might be confused, but still I am only getting comments on the issue/comparisons. That is neither here nor there. I know that you are a very senior, knowledgable and respected person on this Site (possibly a Professor at some University as well I think). Could you please run the two algorithms, the one I posted (on gophne thread #73 I think) and the one that awmayer "reduced" a bit further on in the thread. If you could that present to all your results. If the two algorithms gives the same result/s then I will accept that the two algorithms are indeed the same. Perhaps if you could also advise what the name/source of the algorithm that ewmayer has reduced to...he did not state this in his post...I have taken it on trust that such analgorithm exists. Thanx so much.

MORE COMMENTS....PLEASE STATE THE MATH FOR THOSE THAT MIGHT HAVE MISSED IT. If the algorithms are the same...substitute values into the formulas and report what comes out ! Please! I think everybody is crying out for this. May I suggest that you start with the number 1 or any other number that tickles your fancy. That is what we did at primary school be entering numbers into little squares to make the answer true. For Pete's sake. 
It's literally a transform of n+2>n in you formula and then a reworking it.

2^n1 == (n+1)/2 mod (n+2) 2^((n+2)2)1== ((n+2)1)/2 mod (n+2) Replacing n+2 with n we get: 2^(n2)1==(n1)/2 mod n 2^(n1)2==n1 mod n 2^(n1)== n+1 mod n Casting out the terms that don't affect the remainder we get. 2^(n1)==1 mod n QED edit if this doesn't register you need to brush up on mathematical laws like the law of replacement, or you need to look up what modular arithmetic is.

You can't just apply it to one side of an equation. It isn't the same as the "%" operator in many programming languages, though it is somewhat similar. When we say that a ≡ b (mod n), what we mean is that n divides ab exactly (or, equivalently, that a and b leave the same remainder on division by n). So, for example, 1 ≡ 11 (mod 5), because 5 divides 111 = 10 exactly. When n=5, indeed 2^n1 = 31 and (n+1)/2 = 3. These are not equal, but 2^n1 ≡ (n+1)/2 (mod n+2) is still true, because 7 divides 313 = 28 exactly, and 31 ≡ 3 (mod 7). The "%" operator gives the remainder you get when you divide one number by another. Note that if b = a%n, then a = kn+b for some integer k: that's what we mean by a remainder. Then ab = kn, so a ≡ b (mod n). This is how "mod" and "%" are related. For positive integers, a ≡ b (mod n) is equivalent to a%n = b%n.

@Serge: I heard the "predictions are hard" quip attributed to Yogi Berra, not Bohr. Two names I never thought I'd see come up in the same sentence. :)
[url=https://quoteinvestigator.com/2013/10/20/nopredict/]Here is a detailed investigation[/url] into the history of said aphorism, which concludes that the saying is indeed most likely Danish in origin, but not due to Bohr. This sort of proliferation of attribution is quite common with especially pithy/witty sayings. To use a maths analogy, it's like people later slapping the name 'Gauss' on this, that or the other technique in order to boost its profile and/or legitimacy. (An example I recall from my days as a grad. student in fluid mechanics was something referred to as the "GaussSeidel" method, an iterative relaxation algorithm for solution of discretized elliptic PDEs. About which one of my profs commented, "Seidel didn't invent it and Gauss didn't work on it.")

I work with what I would call [I]numbergrids[/I] a lot, whereby I take the postive integers, but mostly the odd numbers for obvious reasons, and arrange them into tables of varying number of columns, e.g. 01,03,05,07,09 11,13,15,17,19, 21,23,25,27,29, 31,33,35,37,39 41,43,45,47,49 51,53,55,57,59...this being a 5columngrid of odd numbers. Some interesting facts coming from this grid for example would be; 1) The columns filter the primes into primes having the same[I] unit digi[/I]t, i.e col1 having all primes ending with the digit 1, column 2 has unit digit 3, and so on. 2) The grid filters out the mutiples of 5 for a grid with 5 columns, multiples of 7 for a grid with 7 columns, etc 3) The grids have the property that [I]per row[/I] (in a column), the values at that location, have the property of sieving out thevalue at that number of rows further down the column, e.g C1/R2 has a value of 11. All values in muliples of 11 would be composite. In C1/R2 the value is 21 and all numbers removed 21 rows from this location in the column, would be composite. Since 21 is a composite itself, with factors 3 & 7, all values removed both 3 and 7 rows from this location/value in the column would be composite as well. The rows/values not so eliminated are primes. This makes these grids de facto, primality "sieves", which could actually be formulated/algorithmized as well. When I tabulated the mersenne odd numbers vs modulo of the odd numbers (in Excel worksheets)....the quotions became bulky too quickly, I observed many interesting patterns for the results of the modulos...See extraction from the table/grid below; 01,02,03,04,05,06,07,08,09,10,11,12,13,14.......Column numbers Row M 03,05,07,09,11,13,15,17,19,21,23,25,27,29.......Odd numbers 01 01 01,01,01,01,01,01,01..........................................M mod Odd Number 02 03 01,02,00,07,07,07,07,07,07,07,07,07,07,07,07 03 05 01,01,03,04,09,05,01,14,12,10,08,06,04,02,00 04 07 01,02,01,01,06,10,07,08,13,01,12,02,19,11,03 05 09 01,01,00,07,05,04,01,01,17,07,05,11,25,18,15, etc. 06 11 01,02,03,04,01,06,07,07,14,10,00,22,22,17,11 The Mcolumn being the mersenne number 2^m1, and the other columns being M [B]mod[/B] Odd number. From this table many weird and wonderful properties were evident; 1) The Mcolumn also has the sieve property [I]per row[/I] as discussed above (making it a de facto mersenne primality checker) 2) Within a column the modulos repeat itself according to definite pattern commensing with 1 and ending with the column number., albeit not always with a factor due to the primality of the mersenne primes. However, the table exposes a factor for M11 at Column 11, Odd number 23, the modulo returning 00 [I][B]3) The modulo of the row number equivalent vs the column number equivalent was always equal to the the row/column number itself, unless the odd number was composite![/B][/I] Taking this relationship of the modulo for the mersenne number of a row [I]vs[/I] the odd number of the corresponding column, e.g. row 5, reduced to the following; Row [B]5[/B] is equivalent to M9 and Col [B]5[/B] is equivalent to the odd number 11, WITH the modulo = "5"...which was apparently the case for all PRIME numbers (as tabulated per column). The relationship was then, using the rule of "when the [I]modulo of row number equivalent vs column number equivalent = row/column number[/I] being prime", gave a relationship of M[I]n[/I] to Odd number (n+2), when the modulo was equal to the row/column number, being prime. For row 5, mersenne prime was "9", and the associated odd number "11", with the modulo for the function being "5", "5" being the mersenne index [(9) +1]/2.... I finally the reduced this to the formula/algorithm; When [B]2^91 mod (9+2) == (9+1)/2, then (n+2)[/B] is prime according to the pattern that eminated from the table, Generalized, the formula became; [B]When 2^n1 mod (n+2) == (n+1)/2, (n+2) would be prime, else composite.[/B], according to the table I was working with which I took up to about + 301 The table looked like a [I]rosetta stone[/I] for prime numbers (for the column odd numbers) I then saw this relationship (in the table) as a relationship[I] that defines[/I] the relationship between prime numbers and composite numbers universally, with reference to the mersenne odd numbers. That in a nutshell (forgive the pun) was how I derived the "algorithm" that I posted and was so enthusiastic about (without running it properly in SAGEMATH looking for things like false primes, etc, as I am still relatively inexperienced in Sagemath code). An interesting thing about the table was also, in addition to the "gridsieve" property of the mersenne numbers in ColM (as nalluded to earlier), I also thought the table/algorithm could be used to identify "twin primes" tweaking the relationship/algorithm slightly to say that when two consecutive row/column equivalent modulos for the algorithm is equal to the row/column number, then we potentially have a twin prime! , barring false positives of course :( That is it.

Hi CRGreathouse I read up on your link about [I]wheel factorization[/I], and it is unfortunately a bit too complicated for me to understand the math involved in [I]wheel factorization[/I] fully at this stage. It seems as if one would need to have a postgrad qualification in [I]wheel factorization[/I] to fully understand it. What I do is much simpler. I take the positive odd numbers and arrange them into grids of varying column numbers, and then look at the distribution patterns of the prime numbers. For example again, if I arrange the odd numbers into a 3column grid (or an [I]array[/I] as one of the other contributors has suggested that it could be called), all the primes are then distrubuted in columns 1 & 3 respectively, and column 2 contains "3" and all the odd multiples of three. Column 3 contains all the [I]chen primes[/I], as well as all the squares of the odd numbers(including primes) in column 1. Column 1 contains all the primes that would follow after chen primes that is the second partner of [I]twin primes[/I], as well as the squares of the odd numbers (including primes) in column 3). Just some of the more obvious patterns eminating fro a 3column grid. As indicated in an earlier post, these tables have the property of being de facto primality sieves as well. The prime (and composites) in this [I]grid3[/I] distribution are distributed according to 6n+1, 6n1 consecutive order. Again the sieve factor can be algorithmized to identify the prime distribution in this grid. Grids with a prime number of columns, "filters" the multiples of that prime number located in the centre column of the grid. Grids with a composite number of columns "filters" all the prime factors of that composite odd number!! Another potential algorithm! which would read something as follows; [B]For any XXXgrid of odd prime numbers with y number of columns, where [I]y[/I] is an element of the set of odd numbers, then when [I]y[/I] is prime, only one set of odd multiples of [I]y[/I] would be distributed in the centre column of the the grid. If y is composite, the multiples of the [I]prime factors[/I] of [I]y[/I] will be "filtered" on both sides of the grid, with respect to the [I]y[/I](composite)multiples in the centre column.

I'm sure there are plenty of other examples, some better, but a paper I ran across when I was first serously fiddling with these things, shows a number of similar charts (see page 106107 near the end). Arranging numbers in an array and noticing patterns of primes and composites is common.

[QUOTE=MisterBitcoin;476115]Thats hard. It means "Kurbel Gedanke", well thats not even a real word anyway. :smile:
Well the translator is blocked from my office, but I guess you mean something like "besondere Gedanken" or especially thoughts.[/QUOTE] The best I could come up with was exzentrisches Denken or maybe verdrehter Gedanken, but my German is quite poor. I was hoping for some nice compound word, like Fremdschämen or Treppenwitz. Ich habe Weltschmerz weil es kein Wort gibt. 
[QUOTE=danaj;476090]I'm sure there are plenty of other examples, some better, but a paper I ran across when I was first serously fiddling with these things, shows a number of similar charts (see page 106107 near the end). Arranging numbers in an array and noticing patterns of primes and composites is common.
"[URL="http://www.mat.ucm.es/serv/revmat/vol91/vol91e.pdf"]A Note on the Extensions of Eratosthenes' Sieve[/URL]" by Quesada and Van Pelt, [B][COLOR="Red"]1996[/COLOR][/B]. By today's standards this is pretty yawnworthy, but I personally gained some appreciation of the modular patterns from reading it, as well as some ideas for optimizing my SoE implementation back when I first started it (so many things I didn't know then....) I don't think the authors believed they were making really novel insights, but trying to make some helpful clarifications and noting patterns. Feel free to make these connections, not read anything of the previous work in the field, and believe you are a genius first discoverer. That's great. I am somewhat envious. But I'd also know I was lying to myself. "They laughed at Einstein, but they also laughed at Bozo the clown." This is crankthought (there should be some cool German word for this). The more people disagree with you, the more you must be a misunderstood genius?[/QUOTE] Hi Guys, Apologies I had some other business to attend to so I could unfortunately not reply earlier. Danaj, did you read the link/paper that you posted. If you have, which i doubt, I think you simply "googled" a paper which you thought might support your argument. Honestly, if you really think that is EASY math, equivalent to what I have introduced to you, then you need to change your medication. I leave it to all the hundreds of neutral readers out there to decide. I shall be happy with that. I am in the process of preparing to submit my algorithms to other sites/forums, as well, SO THAT ANY FRAUDULENCY COULD BE EXPOSED FAR AND WIDE, but not by an apparent biased grouping. Look I might be proved to be the world's greatest fraud in the end, but I believe in my own integrity. That there might be work out there that predates/expounds on what I claim/submit is not at issue, being cogniscent of the wealth of brain power that is involved in the field of math all over the world. But what I do know that soon very soon at least one reader/contributor would appraciate what I have "discovered", much of which I have not posted, fearing a witchhunt of the order of the Inquisition of the Dark Ages. The more times change....the more they remain the same. On this site, I don't expect a symphatetic ear to anything I say, sad but true. I don't know if there are any other contributers that get that feeling as well, or if i am imagining myself. However, very soon (about a month or two) if I would be able to still post, I would like to attempt a Proof for the Twin Prime Conjecture. Not sure if it would be a valid proof.

[QUOTE=LaurV;476122]I also wondered that, for the last 15 minutes I wasted of my life, reading this thread. The pattern is bottypical, but I don't think he is a bot, he is just a trlol. He knows some math terms and knows how to use them in context, which is quite difficult for a bot. It is not just Eliza, like storfly and other "guys" we had here around. This guy is more in the "cmd" category.

Are you openly propagating censorship and oppression of ideas (scientific or otherwise) in this day and age? Are you even from this planet? If you are serious, then I have no words for you, and won't be commenting on any of your posts in future. But you can continue to post whatever you like on this forum, no problem, since it would add to the debate.

Seriously. For your information I am contesting the verdict that the algorithm in question was in fact a copy or clone (of Fermat's Primality Test or another)...BUT NOT ON THIS SITE OT THREAD, I promise!!!!!! I am contesting this finding on five grounds (I am working with friends who are having another closer look at this matter and the supporting premises for the current accepted status, much of it which is due to my own acceptance of the suggestions of sameness), but the conundrum is this as well....I am such a dunce, why is it that when I accept suggestions of the "sameness" of the posted algorith, I suddenly become a guruji. For you information, should you be interested at all, which I doubt and don't blame you for, and won't bore you with it as well! the grounds for the contestation are the follow, just for the information of other readers; 1) Fermat's Primality test works with congruancy, whilst the accused algorithm works with equality (changing remainders for changing inputs) 2) Reducing the formula's of the two algorithms to standard form, [B]LHS mod x[/B], furnishes different dividends. 3) Changing the base of the dividend from base 2, does not furnish the same remainders. For Fermat's Primality the remainder/congruancy is always one(1) for prime witness. 4) Fermat's Primality Test does not utilize [I]mersenne numbers[/I] at all! the accused algorithm has the mersenne form as the dividend of the algorithm! 5) Running the suspect algorithm for false negatives up to 1,000,000 none was found This has been confirmed unintentionally by one of the senior contributors on the site that was running the algorithm in Pari, I think check some of the earlier posts. Fermat's Primality check has a problem with false negatives (Carmichael Numbers). It is only over once the fat lady sings, but this is not for this Site or Forum. Thanx and regards.

I shall take to heart all you say and model my responses making use of your counsel. What can I say, ever since my first post on this thread, making [I]outlandish[/I] claims, you have been very positive yet authoritive in demanding a professional standard w.r.t claims made, research done, supporting evidence required, etc. You came/come accross as a Sage who can see the folly in other mortals, but do not stamp on them like they are insects because of their ignorance/stubbornness/foolhardiness. For this I thank you, and I think I speak for many others, especially the inexperienced contributors on the site. Whatever happens on the site/thread in days to come, I will only have gratitude for your approach, even to the unwise, as I admit I could be, or possibly am.
