Seeing that 287897772… is now scheduled for GNFS on 16e_small, it would seem prudent to cease all further ECM on that number.
Together with whatever Sam has run, that's probably enough ECM for the c202. The c204s can have some more while we wait for polynomials. Thanks Ryan!

Hi, guys, I'm looking for a good poly for this C184 coming from aliquot sequence 933436:i12610
My best so far:

I'll take a break from polyselecting during summer.

Thank you! The second poly is the clear winner.

A better result from CADO:

Which cownoise scores as 4.5876e-14 at skew 57783690.79274.

I’m waiting on a final run of msieve-GPU to finish later today.

msieve-GPU spit out a poly scoring 4.29e-14, details not worth reporting. Abandoning msieve-GPU.

Continuing with CADO, should have results by mid-week.
