swellman 2017-05-20 12:17

Reserving 131^69+69^131 C202 cofactor (15e).


The C191 from aliquot sequence 3408 (step 1668) must wait for my big machine to finish its current task, around June 1st.

I'll take 134^116+116^134 next.

fivemack 2017-05-23 15:24

Taking C208_147_50 (ETA now morning of 1 June)

swellman 2017-05-23 17:37

I'll take C211_125_112 though it could probably use a few million more relations. It's actually a 32-bit job (the 14e status page erroneously lists 30-bit).
