578M raw relations got me 391M uniques, and a 39.98M matrix at TD=84.

There was a deficit of 27M in relations vs ideals in the first step of filtering, so I'm continuing to sieve. I think 610M or...

No, I didn't use 162M uniques. Did you miss a zero? This job is tougher than the GNFS-207 by quite a lot, and uses bounds which are expected to require more relations (36/33 should require more than...

56M relations, ETA is now late Wednesday. Surely that will lengthen when Ed's farm naps, but that's impressive for a day's work!
