I guess you probably haven't played many different versions of the Monopoly board game. There are flat land, 1 house, 2 houses, 3 houses, 4 houses and a hotel which equals to 5 houses. The skyscraper equals to 6 houses in the Mega Monopoly edition. I've thought that every bit of trial factoring done by me add a house to that specific property or exponent. P-1 and P+1 also stack up the task towers. If I finish up the trial factoring of an entire block such as M168,202,000 to M168,203,000, then I own an avenue like a whole set of properties in Monopoly.

I've only believed it's very cool to own an entire Mersenne block of the exponents like Roland Clarkson from M160,374,000 to M160,375,000, mostly written in his big name.

Everybody prefers different works I guess. When more exponents under M200M are factoring up to the recommended bits with the corresponding P-1 done, UncWilly is more pleased since the waves of the crowds will reach there within at most a decade anyway. For exponents slightly larger than M332M, efficiently finish up the trial factoring to 2^81 will take a more advanced GPU.

The TF and P-1 tasks I wrapped up in the M168M are there forever. If the new factors are found, then those add up to the total which my father requires to me to have before asking for a new very high end PC.

Until someone reveals the next hidden Mersenne Prime, there's really no correct or incorrect ranges to work on. Why should everybody be crowded in the same area with so many rules to follow while other areas are nearly empty?

I don't want to end up poaching lots of Mersenne exponents just because I like certain numerical combinations better. Most M168M exponents are not assigned to others with the extra restrictions to me.

I only want to establish a headquarter for myself on M168202123 where I perform every type of task to the higher levels, bits or bounds, at least the upcoming missions and tasks will be easier according to the mechanisms in some of the video games I play. Exploring the archaeological treasures are more doable with a taller central operation building nearby the digging sites.

There's a moderator named M344587487 in this forum, he has his very own exponent to specially represent him.

Most people crunch what is doled out by the PrimeNet server, be that automatic or manual. I believe this how, by and large, all of GIMPS primes have been discovered. The herd wins every time.

I won't concede until Mersenne.org officially post "All exponents below 169 million tested at least once." on the milestone page.

I'll patiently wait for an answer until year 2027.

The dozenal numerology I've used told me all the Mersenne exponents from the current wave front up to M167999989 will be composite.

Let me finish my skyscraper headquarter on M168202123 first. Maybe own an entire avenue there soon. Search efforts should be easier afterwards for the gaming concepts mentioned above.

So I just got NF-PP1 on M168202123, it showed the result "Start=2/7, B1=1600000, B2=65000000", why my previous NF-PM1 counted as 1/7? I'd like to know the chance of it being a hidden Mersenne Prime at this point using UncWilly's knowledge.

Upon your so many NF-PM1 entries, the exponent block of M105211111 grew so tall that it occupied almost my entire screen resolution, thus as tall as the World Trade Skyscrapers in Cities: Skylines.

This is barely even English. What are you even attempting to say?

Are you accepting my offer or not?

Not now, I have to finish the PRP of M168202123, bringing all the M168,***,*23 to at least 2^75 before I jump into that step. Give me some time to factor up more candidates to 2^78. If I don't have enough clues about the existing factors from both TF and P-1, I can easily lose a bet to you.

Here's my current list, I want to ring out all the F-PM1 before risk the 5 on you. I already booked room 202 for myself.

Available M168,***,123 candidates as of 08/19/2021

043, 062, 080
133, 139, 140, 160, 163, 175, 184, 196, 199
217, 251, 253
311, 316, 377
416, 442, 461, 464, 484, 485
505, 506, 526, 530, 548, 595
602, 607, 638
710, 752, 776, 784, 791
871, 883, 898
922, 931, 932, 934, 937, 965

The red fonts indicate that the exponent is PRP Ready.

2 of my friends from the same family have a 3080 Ti and a 3070 Ti, bring up the TF bits seem to be only a piece of cake there. For some reason, even they want to topple my main skyscraper down by finding a factor on that specific exponent. They still want to try on the higher bits during another free weekend. My dozenal math have surely caused other people the desires to react strongly towards me, either feel extremely weird or laugh endlessly.

All I said was "My dozenal math indicates that the primitivity of M168202123 is very high."

This is what I've meant for an Avenue -> https://www.mersenne.org/report_expo...8203000&full=1. I'll start to write my name on all the unfactored exponents within this range. M168202123 stands tall as of today. No signs of any factor locates nearby my current working area. I'll keep up the fun with more TF on other M168,202,*** exponents to own the entire thousand range.

Both ViliamF and you tried on M103237441, it survived nicely until the completion of the PRP test.

If I have the chance to launch 1,000 attempts, enough to finish all the M168,***,*23 candidates. I'll be a different story.

Unfortunately I don't have friends who own AMD Radeon 6900 XT, thus I must do the PRP myself. Gamers typically prefer a fast Nvidia GPU with a mid-end AMD Ryzen 5600 CPU.

By the way, I found another factor between 2^75 to 2^76 on M168412721 yesterday.

Is that even a known math term? If so kindly provide a link to a good definition.

Raydex's M52 guess was proven wrong in ~37 hours from the guess post. It had nothing to do with you.

I prefer to set the range using exponents without the known factors such as M154900667 < Mp#52* < M181503583

Isn't Drkirkby's 20 consecutive NF-PM1 benchmark testing on M105211111 like this too? I want the NF-PP1 skyscraper similar to his NF-PM1 tower model.

It takes 39 hours to finish 1 NF-PP1 and 24.0 days to complete the PRP on Intel Core i7 4930k for M168202123. So if it only takes 12 hours on a friend's machine or a PC in the computer lab, then the PRP of the same exponent can be done with around 7.38 days. AMD Threadripper 5970X suppose to be almost twice powerful as Ryzen 5600X. If Windows 11 can handle 32 threads on Prime95, then running lots of M168M PRPs shouldn't a hard task at all.

I don't want to try PRPs outside my home, it can take a long time to upload the proof file especially without AMD Radeon 6900 XT, but NF-PP1 only takes seconds to code in.

Let's wait for another year, if not at least 1 new Mersenne Prime drops down within this range, then the probability is likely only the audience polls collected from the public resources.

If instead you spend $2000 today, and another$2000 in 2 years time, it will have cost you the same over 4 years, but you will get better throughput. A $2000 computer in 2 years time is likely to have much better performance than a$4000 computer today.
I sometimes make unusual deals with my friends such as they can put their sweat shirts on my face if a factor is found on M168202123. The key is to be able to access more computing powers although with a chance to pay a price in a different way.

I made up my mind that I'll get AMD Radeon 6900 XT after its price drops down to \$999 or less unless AMD Radeon 7900 XT releases early in 2022.

Primitive seems to be a functional math term: https://en.wikipedia.org/wiki/Primitive

The primitive triangles in particular link to the basic ratios of the numbers.

This is exactly the reason why I believe M168202123 has the much stronger prime-like characteristics than M168173321.

The dozenal base categorizes those further into (5, 7) enders and (Ɛ, 1) enders.

Any M168,***,*23 if locates within a twin prime set must be the upper exponent because all the M168,***,*25 are obvious composites.
