 2014-06-29, 16:33 #860 TheJudger     "Oliver" Mar 2005 Germany 2·3·5·37 Posts Hi, just an hour ago "I" found this gem: P-1 found a factor in stage #2, B1=620000, B2=12710000, E=12. M67825453 has a factor: 1722206812177416217749744344545878167459479 (140.30 bits) k = 12695874011909778308076647453765463 = 3 * 17 * 29 * 79 * 1447 * 24481 * 31039 * 349529 * 378277 * 747427 Should be my second largest P-1 factor so far.

Hi Chris,

I get them from here.
A small shop with good prices and nice sales persons. And when you buy several exponents at once they grant you at small extra discount.

Bizarre factors

I got one today:

Code:
ECM found a factor in curve #2, stage #2
Sigma=7053813379423454, B1=3000000, B2=300000000.
UID: ANONYMOUS, M27529 has a factor: 9662183525912193406922912529583 (ECM curve 2, B1=3000000, B2=300000000)
k = 3 * 31^2 * 433 * 6988773391 * 20115060971

This k is quite rough.

I have just begun this quest ...

 2014-07-23, 10:45 #864 lycorn     Sep 2002 Oeiras, Portugal 3×13×37 Posts Wow, that´s a really nice one! But you´ve not reported it yet, did you? It doesn´t appear as Factored, on Primenet pages.
 2014-07-24, 00:22 #865 PageFault     Aug 2002 Dawn of the Dead EB16 Posts The reason is that the manual results page won't accept it. George has been advised. There will be more of these. It takes quite a few curves, somewhere in the order of 6 to 7 thousand, should I count them. No biggie, just takes time and in time I'll move this onto all cores. At 15 000 curves per week, I should find a bunch of these. Crunch on folks, happy hunting!

I don´t see any reason why that should happen, apart from the periodic glitches experienced by Primenet. Try resubmitting the result, as you may happen to have tried during a Primenet outage. They´ve been rather frequent lately, unfortunately.

 2014-11-16, 03:28 #867 PageFault     Aug 2002 Dawn of the Dead EB16 Posts An interesting one came up today: Code: ECM found a factor in curve #306, stage #2 Sigma=563592846122112, B1=11000000, B2=1100000000. UID: ANONYMOUS, M25849 has a factor: 490089625697694370568455713655482757513 k = 2^2 * 3 * 179 * 271 * 208274569 * 78191933955159820247 k is just a bit rough. 5100 curves at a lower bound and 306 at the current bound and I came in just below the bound! I wonder how long until I work through to the next bound ...

 2014-11-18, 03:40 #869 PageFault     Aug 2002 Dawn of the Dead 5×47 Posts Those are very smooth, nice finds. I assume they are P-1, Stage 1 factors? I have one from a few years back, somewhere in a backup. I'm seeing my ECM finds to be all rough, although my data is lacking. Crunch on, happy hunting!
