Preferably another 2*t50 or t52 worth of curves run on this number before GNFS, but it is still available and has been assigned to you.

Line (13, 5) c171 probably needs 2*t50 worth of curves but is also a GNFS target.

First 4 way split

Ran to t45 + half a t45 worth of t50 curves so a small ECM miss.

By far my biggest ECM miss to date. Survived 1500 curves at B1=43e6 without finding any factors, though this completed with a nice p80 * p80 sub-split:

Just finished t55 ECM on (9, -6) c178, no factors. Unspun poly is also SNFS 229, so this one seems to be right on the edge.

Based on sieving results from my c202 job and a comparable GNFS job I believe the snfs quartic should be slightly easier.

Seems like 3000 digits (for the size of the full discriminant) is around the upper limit of the numbers we can reasonably completely factor unless we get quite lucky with ECM. I'll focus on those...
