Getting others to do the work on exponents I like (was: Trial Factoring Progress)

[tuckerkao]

The F-PM1 result of M168433049 was just reported, it seemed like the M168.4M subrange is no longer standing much higher than the 2,000 unfactored milestone line.

Well done.

We all stand on the shoulders of giants.

If we take the early 332M exponents up to the recommended level while SRBase takes 10,000s or 100,000's of the later ones up a couple of bits it will help us a bunch. And it will save a bunch of wasted time on PRP's that could be avoided.

Please point out at least 1 M168M exponent that had a wasted PRP because of the insufficient trial factoring or P-1.

The LL test of M168341081 was wasted because it was the wrong working type. Same reason for M168961139. M168288023 had 1 LL test, if it were a PRP test, it would have most likely been certified.

The PRP of M168744287 didn't have the certified status because it was tested before the proof method was introduced.

My Prime95 couldn't generate the proof file for M168286523 back more than 1 year ago, I shouldn't change the Prime95 version while a PRP test was going on, the trial factoring was abundant.


So far, my method saved the PRP tests of M168104323, M168113423, M168621923

You left out the part where I was talking solely about the 332M range. That is what I was referring to at the end of the quote.
In context...

If you do a deceptive quote like you did above again, you might get a break of a couple of weeks

Maybe I misunderstood this quote, I thought you meant me. Maybe you meant another user.

When I was talking about 168M, yes, that is you. But, talking about wasteful PRP's in the 332M range is not about you. There have been factors found in the 332M range on numbers where people were doing or had done LL's. I have been working in that range since the mid 2000's (and have many of the factors below 70 bits. Even then people were skipping taking the exponents up to 77 before starting the LL (they were hoping to find the winner for the next EFF prize). So, letting SRBase do some of the work helps with the goal of preventing unneeded PRP's. It is a case of working smarter by taking advantage of free help.

The 480 M168M exponents remained at 2⁷⁴ several days ago would only take me a total of 4 days to bring them up to 2⁷⁶, so a small difference in timing for me. SRBase will only work up to 2⁷⁵ during the Q1 2023 trip, so even less GHz Days total.

What I want is the PRP help. How about you specify what I need to finish prior to earn a free PRP test of my choice on 1 M168M exponent that a moderator like you or ATH will run?

For every 8 consecutive weeks you refrain from posting on the forum I will run 1 PRP (exponent of my choosing) in the 168M range.

Since I've already posted today, the earliest possible starting day will be tomorrow Dec 24th, 2022 server time.

So if I fulfill the 8 consecutive weeks promise(56 days nonstop), how long later will the PRP test be started and be finished? I propose -> Be started within 2 weeks and be finished within 60 days.

Be specific, I want it to be an exponent in the M168,***,*23 format. There are several hundreds of them to choose on this list: https://www.mersenne.org/report_fact...=79&bits_hi=84. If you agree, then I agree.

At the fulfillment of the 8 weeks, you can PM me and I will start the PRP test on the exponent the next practical chance I get. I currently don't have the data at hand to know how quickly the machine I will use will take to finish, but it will be a reasonable time. Again I said that the exponent would be one of my choosing in the 168M range. I will add that it will be an exponent in the Primenet database (the exponent is prime) that has not been verified composite (this includes that it does not have a known factor), it will be one that is not currently assigned at the time I start the test, and I will use PrimeNet to get an assignment for it. Other than that, I will not accept further restrictions on the exponent.

Looks like we have reached the deal here. I'll continue to do the PRP tests of the M168,***,*23 exponents using my own machines until the winning and/or losing scenario has been announced.

Winning for me: 1 of the M168,***,*23 turns out to be a Mersenne Prime.
Losing for me: All M168,***,*23 turns out to be composites or another user finds a new Mersenne Prime smaller than M168M and larger than M82589933.
