Fantastic, thank you. Sieving is already done, filtering is running with LA to follow. Should have factors sometime tomorrow I'd guess. Since this one was so similar in size to the last, I reused most of the parameters. But I ran 15e with 31/29 instead of 14e with 32/30, and adjusted mfb's downward correspondingly.

C203 from (3,-9) factors as:

Taking (6,-8) c179. Test-sieving suggested SNFS is slightly faster than GNFS. There was very little to choose between Max's two spun polys so I went with the first one. I'm using I=15 and lpb 32/30.

sieved for about 6500 thread-hours for Q=7.6M - 84M

P51 * P158; possibly t55 ECM would have found the factor faster.

Is (12, 0) c147 still unclaimed? I'll run it to t50 while seeing if someone else hollars at me to desist. If it survives and no one else is running it, I'll GNFS it.

Doesn't look like it, reserved it for EdH.

(10, -6): The only thing left is the c258, which has survived t50.
