:w00t: I know you had a record of 127 bits, which honestly I have very little chance to beat it, many years from now, but I am coming to get you for lifetime credit... , get in the hundredth percentile on the leaderboard, and then I will go back to DC, and let some cores doing P-1 under 1M with very high limits. There is where the big factors come from. What do you know, I might get lucky! :razz:

We'll see if I follow your plan like a puppy. :razz: But if you do pass me... just know that I have only a little over half my power running P-1 at the moment!

Anon on machine toma4tti found a factor by P-1:
332245861 has a factor of 514701206225822215282489657
reported on Nov 16 2013 @ 10:46PM 64.0 GHz-days 88.7 bits

Uncwilly 2013-11-20 00:55

I had one machine find 2 factors in 2 days both P-1 stage 1.
64317947 has a factor of 52744473176262272623601 [B]75.5 bits[/B]
64320973 has a factor of 4171438018009522530410037151 [B]91.8 bits[/B] :shock:

Uncwilly 2013-11-25 05:37

I had 4 machines hit with P-1 factors in a single day and 2 more today. One of these is my personal best:
64,489,937 has a factor of 177801640586828840036267140893769
[B]107 bits[/B]:wacky:
[B][I][FONT="Comic Sans MS"]k[/FONT][/I][/B] = 2[SUP]2[/SUP] × 3[SUP]2[/SUP] × 7 × 53 × 257 × 269 × 283 × 1399 × 4799 × 785773

That a nice one for Stage 1.

It's odd because I can go a week or two with no P-1 factors and then I've had 4 in the last week also. One is a nice Brent-Suyama:

[URL="http://www.mersenne.ca/exponent/64455383"]M64455383[/URL]
B1: 910,000
B2: 20,930,000
k = 3 × 19 × 89 × 109 × 557 × 464825197

But, it's nothing compared to markr's Brent-Suyama find on 18 Nov 13:

575,00010,350,000

k = 2 × 154429598075412

You are on a roll. What memory settings do you use on those systems?

go, go, go! Factors > 2[SUP]120[/SUP] at the current P-1 wavefront aren't every day founds. Seems that you got all [I]my[/I] factors, I had a bad series of nearly 300 P-1 assignments without any factor last week!

A factor is a factor is a factor, for GIMPS purpose it doesn't matter what kind of factor it is (small, big, smooth, ...) but humans might have other feelings.
My feelings about current wavefront P-1:[LIST][*]<2[SUP]100[/SUP]: yet another daily P-1 factor[*]2[SUP]100[/SUP] to 2[SUP]120[/SUP]: OK, somewhat bigger P-1 factor[*]>2[SUP]120[/SUP]: hurray, big P-1 factor[/LIST]There are some exceptions, ofcourse[LIST][*]very smooth stage #1 factors[*]Brent-Suyama with 10+ times above B2[*]composite factors (in other words: multiple prime factors at once)[/LIST]
