Those are both moderately large 15e jobs; queued

The first number has a p51 which needs to be removed from n. Not sure if it is still an SNFS job.

[QUOTE=XYYXF;450450]Have these ever been queued? :-)[/QUOTE]

Sean asked them to be removed from consideration until he had run some more ECM on them. I don't think there was ever an update after that.

[QUOTE=RichD;450455]The first number has a p51 which needs to be removed from n. Not sure if it is still an SNFS job.[/QUOTE]

Good eye! I must have found this poly before the p51 was hit by yoyo@home and then never updated the poly file. Rerunning Yafu, it spits out the same three candidate polys but now slightly prefers a sextic after test sieving (though still 15e siever): The poly given originally in my earlier post is still very close to optimal and can be used in sieving if changing the poly file would be too painful at this point.

I don't think GNFS would be faster, and Yafu wants SNFS

[QUOTE=jyb;450464]Sean asked them to be removed from consideration until he had run some more ECM on them. I don't think there was ever an update after that.[/QUOTE]

I ran ECM on both for 1000 curves @ B1=3e8, and yoyo ran full t55 on each. Not a ton of ECM admittedly but enough for reasonable due diligence I think, Didn't bother to suggest them for the 15e queue as it was pretty full, but now some of the harder composites have been sieved so I say go for it.

14e Candidate
 

C230_132_73 survived ECM to partial t55 and t60.

Anyone have some factoring jobs for 14e? Running dry again.

I am currently running ECM on C222_125_92 but it will be 4-5 days before it's ready for NFS at current pace.

13*2^789-1. ECM of 2.2t50 has been run:

When the grid ran 13*2^784-1 for me, it produced 250M rels for a 31LP job; the matrix was 6.8M at TD 130. When I did 13*2^786-1 on my own, ~290M rels for a 32LP job produced a 7.5M matrix at TD 110.
I'm pretty sure if this was run as a 32LP job, I'd be able to build a matrix with TD 130 given 330M raw relations. I'm also pretty sure 330M 32LP rels is less work than 250M 31LP rels; whichever is chosen, I'm good with 240M 31LP rels or 330M 32LP rels to solve the matrix. If queued, I'd like to run the linear alg myself.
