Decent-sized penultimate factor; 81 hours on 6 threads i7/5820K for 12.9M matrix at density 120. The attached log file is long because it records earlier filtering attempts with fewer relations that made an unacceptably huge matrix.

Bother, I forgot to leave C200_150_148 running over the long weekend. ETA probably next Monday morning, 9 May.
