P-1 factoring anyone?

I just submitted the whole results file, since it had never been sent to your site before.

In the new scheme of things, if P-1 doesn't get done then when an exponent is assigned to an LL tester he must do the P-1, last 2 levels of TF, and then the LL test.

If not enough people sign up for P-1, I'll have to tweak "do what makes the most sense" to assign some P-1 factoring. We have plenty of time to work this out as the leading edge of exponents that need P-1 factoring and are holding up TF is above 48 million. It will take a while before the leading edge of LL gets that high.

I have some comment, but I don't intend to get bard again.

Found another B-S factor. http://mersenne-aries.sili.net/expon...etails=8521171 (results file not submitted yet)

edit: Also have 13 bad prior P-1's on 8.5M so far.

What B1/B2 did you use?

According to http://mersenne-aries.sili.net/expon...etails=8521171, B1=45000/B2=686250 (Look on the "Actual" line at mid-page and under the "P-1 results:" close below that.)

That was the original P-1, since a factor was found, it does not show the new bounds.

Okay. I just figured that you'd submitted the result between post #1224 and now.

Also, under "date found" it says "2 May 2012".

Is 48292035869045144656328161 the factor you found?

I'm puzzled about how the numbers on the page are consistent.

Yes. James' site picked up from Primenet that I submitted that factor and credited it on the 2nd, the day it was submitted. Since I have not yet submitted the results file to his site though, it does not show the updated P-1 that I performed. If you look at http://mersenne-aries.sili.net/expon...etails=8598691 for example, you will see that I have submitted that results file. I usually like to have a sizeable file when I upload results, plus procrastination hapens.

Which is fine, you can upload as big or small results file as you like to my site. However, if you're going to comment on P-1 bounds and refer the data on my site, it would be helpful to the rest of us to see what you're talking about if you submit at least that single result to mersenne-aries.sili.net first so we can see the pretty graphs.

For those who are fascinated by P-1 factors found thanks to the Brent-Suyama extension, I now have a list of known ones here:
http://mersenne-aries.sili.net/brent-suyama.php

Note: there are certainly far more than the 84 currently listed, but they'll appear slowly over the next few days as I crawl my database and fill in the k factorizations (and thereby the minimum required B1/B2 to compare with the actual B1/B2 used).

Nice, I have two in the list and I didn't even know.
