 2013-09-30, 13:13 #78 wombatman I moo ablest echo power!     May 2013 6C916 Posts Matrix built on the first try (big thanks to Curtis for a tip regarding that). I have to run into work, but the linear algebra is slated to complete in a little under 3 hours. Once the factorization is complete, I'll add the factors and post here.
 2013-09-30, 20:53 #79 wombatman I moo ablest echo power!     May 2013 33118 Posts Linear algebra is completed....currently slogging through Dependency #6. Hopefully this one will be the winner. And it finally finishes! Code: prp61 factor: 1583924529349827397825874704668342404057384620746627769701809 prp82 factor: 2991769695089351239827325745916018206760356961053692232524303469333793399002903159 I've updated factordb. The newest line is a C161. Last fiddled with by wombatman on 2013-09-30 at 21:26

 2013-11-05, 01:03 #88 RichD     Sep 2008 Kansas 309310 Posts i2098 (C165) It looks like the best poly for this number is this one. Would NFS@H be interested in sieving it? Seq 4788 is right behind in poly selection. Maybe a team sieve on this composite, depending upon everyones work load.
