Thank you, Gimarel!
EdH's script already found a 1.327e-15 spin after 1.5 hours of work. It's getting posted here later.

One good runner up so far with a different c6:

The best one so far has E = 1.329e-15 (same as listed in #123 but with the skew adjusted by cownoise):

Best from this range was worse- 2.412e-9 CADO score, 8.55e-16 cownoise score.

Trying one more range: 50-100M, incr=4620, P=12M.

VBCurtis · 2020-12-07, 18:27

50-100M also produced an uninteresting poly, 2.36e-9 CADO score. I didn't bother scoring it on cownoise.

I'll take a break from poly select on this; if we go a week without anyone mentioning their own work, I'll proceed to test-sieve a couple of the Gimarel polys / spun polys and report back.

My university's finals are next week, so a test-sieve update may be a couple weeks.

I'm getting about one poly above 9e-16 every two days. But I have only one other poly above 1e-15:
