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.

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.

Now down to a C131 with this 30-digit prime factor:

Code:
P30 = 324581894996760411403053781829

1000 curves at B1 = 1e6

Well, so much for an "easy" time:

Final count - time to move on.
2200 @ 11e7 - nothing.

It's time to sieve that composite.

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.
