Default Base-2 Miller-Rabin rules.

Using this seminal post from flouran as the basis I can now test Mersenne numbers for primeness exponentially faster than the ridiculously slow LL rubbish everyone is using now. And since, as is shown here by jasonp, the odds of failure are vanishingly small (<=25%), we only need to use a single base-2 Miller-Rabin test.

And not only that, I have discovered a lot of primes that you all have previously missed (proving that the LL test is complete rubbish). In fact, so far, every number I have tested has come up as prime. I have been so lucky to pick only prime yielding exponents that I should buy some lotto tickets. So boo-yah to whoever decided to use the LL test, nyah nyah nya nyah nyah. Base-2 Miller-Rabin rules.

Default The Mersenne prime generating formula!

For all natural m>1 (2,3,4, ...) the following will always generate a Mersenne prime:

p=3*((2m-1)/3)^FLOOR((Sm-2 mod (2m-1)+2)/(Sm-2 mod (2m-1)+0.9)-1)

where Sk is the familiar Mersenne test we all know (I shan't insult you all here by giving the formula, you already know it. ... Actually on second thought I will ...) S0 = 4 and for k > 0, Sk=Sk-12-2

I hereby declare that I have completed testing ALL exponents above 43112609 up to 1 trillion. And they are all prime! I hereby claim myself as the first discoverer for all these Mersenne numbers. Yay for me. So now it is up to all of you to go ahead and test them as double checks and you will see I am correct.

Now, if by chance you test some exponent and find it to be composite, well, umm, sorry about that, I guess my computer had a problem. Of course when you test an exponent and it comes up prime then remember that I found it first, you are only double checking.

Please send my EFF prize cheque promptly, I badly need the money to buy lasers for my pet sharks. Thanks.

PS: I don't care about split infinitives. So what. It was good enough for Star Trek.

A quack post forum? I'll try my best. I apologize to maths for this:

Hello, friends. I have discovered a BRAND NEW formula that generates ALL the prime numbers, and can factor any number! Of any size! Forget all that SIQS and GNFS nonsense! This revolutionary, groundbreaking new formula uses a quantum factor finding system, that can factor any number, in seconds! Here's proof!:

The quantum factor finding system is so effective, that RSA would be compromised as is today. This is why the quantum factor finding system's mechanisms remain secret.

For one that's so quick to criticize others, you are excellent at being a kook. Have you been reading lots of kookery recently?.. Dammit, I just walked into that one.

  • from the factorization N=pq you have, deduce the private key d = 1/e mod (p-1)(q-1) corresponding to the public key e=65537;
  • compute c = 3d mod N;
  • send the integer c to me (or publish it on some web page);
  • on my side, I will compute m = c65537 mod N and check that m=3.

Default Brand new technology for Mersenne primes

Hello, friends. I have a REVOLUTIONARY new technology for finding MERSENNE PRIMES!

Stop using that LL garbage! That is outdated and USELESS! Try our revolutionary new method that uses consecutive division, to find super large Mersenne primes!!

The divisions take place in a very very short time! Our machines use revolutionary quantum technology to test for numbers no one has ever dreamed of testing before.. And we have found a very large Mersenne prime! We have broken a record here!!!

Here is our Mersenne prime:

23971024427881617784446989042698959305737250294982092756939591767576453404439030489955509227409721981924650383025441722461857496719966418363269236629669728139979470828471218304117361-1 is a prime number!!
Here is our data:

Elapsed time: 0.000000000000245671 seconds.
Also: We have made so many improvements to the factoring algorithm, that its factoring run time is:

I cannot do that, as you will steal my work! It's.. It's a CONSPIRACY! You're all out to get me, aren't you?? I'll expose you for the algorithm-thieving morons you are!! I'll expose you soon enough!! I know the truth about you and your little thieving cronies!! I won't let you ruin my discovery and hoard my credit!! I won't let you ruin my reputation!! This is obviously an attempt at algorithm thieving! I saw right through your obvious charade!!
