This concludes my search; I spent around 625000 core-seconds on poly select.[/QUOTE]

Thanks for the two polys, Mike! I greatly appreciate it. I will test sieve these two.

I split the poly-select run into two pieces, so that I could get two "best" polys; CADO by default only keeps one, and I haven't yet explored how to pick out the second-best. I'll have another one this afternoon for you.[/QUOTE]

I can quickly run it through CADO and let you know what falls out.

C158 poly
 

@richs
Nope, your last poly can't be improved by CADO.

C180_132_95
 

C180_132_95 of the XYYX project is the composite cofactor remaining after yoyo@Home found a p56 in C235_132_95, thus shifting it into GNFS. I've begun searching in the 1-100K range and already gotten a nice hit.

The high water mark for a [url=http://www.mersenneforum.org/showpost.php?p=478855&postcount=86]C180 is 8.726e-14[/url]. Can we find a 9-handle?

I’ve completed 1-100K and found no more flares for C180_132_95. Now working 100K-500K range.

Any help would be appreciated.

OK, I'll do 1-2M.
