I can take care of C222_117_100b.

swellman · 2015-12-17, 17:28

I'll take C164_3408_1595.

swellman · 2015-12-20, 17:21

Finally got matrix built for 142^141+141^142, now in LA. Should be factored on or about Jan 20.

9.9 hours for 5.1M matrix on i7-4930K -t6; wildly over-sieved for a number this small. Log attached. Target_density=130 failed to make a matrix ('Sat Dec 26 17:45:04 2015 matrix needs more columns than rows; try adding 2-3% more relations') but td=120 worked.

I'll be starting F1297 when the i7-5820K machine arrives on Tuesday.
