C173
Any help that folks can provide in finding a poly for the C173 of of Aliquot sequence 434040 i3116 would be greatly appreciated. The composite has been ecm'ed to t53. My intention is to sieve on NFS@Home.

Nothing better found. Stopping search.
Perhaps the top poly can be spun up a bit more? ETA: meant to say end of search via msieveGPU. CADO may be able to find much better. Last fiddled with by swellman on 20211121 at 11:56

Thanks for your efforts, Sean. I'll wait to see if Max can spin it up, and if you find anything better with CADO.

Here's a reasonably good poly
Code:

I’ll let my current CADO run finish up but then I’m done searching.

My CADO search finally finished  didn’t even break 3e13! My poly search is now terminated.
I updated the record escore for c173 to reflect Gimarel’s result. Note that efforts by EdH and Max0526 to spin Gimarel’s poly a bit higher found nothing substantively better. Ready for GNFS. Last fiddled with by swellman on 20211127 at 01:01

Another C180 needs a good poly, here is my best so far.

I'll try to help, but I do not think i'll be very lucky. I can't get the gpu version pf msieve153 to work. The only one wich work with a gpu is msieve150. This version of msieve can't use stage1_norm and stage2_norm restriction.
