9_266+.C255 on 14e needs more relations I think.

C186 from Lucas(1384) on 15e has never started to sieve.

Taking F1361

RichD · 2018-01-26, 14:52

Taking C220_129_109 (15e).

wombatman · 2018-01-26, 22:01

Since I requested it be added, I'll take HP10_10319 when it is sieved.

Sean: I accidentally reserved L3865B, which I think is your fox (since you found the polynomial and did the ECM): I've removed my reservation, could you confirm that you plan to do it in the medium term and I'll put your name on it?
