Anyone run ECM curves on c158@i1649 ? No updates since June 29.

Looks like someone was poaching on Dubslow but then got bored. Maybe it was unintentional but poaching nevertheless.

Anyone want to reserve this sequence? I have no resources to spare currently.

Dubslow? Yours was the last reservation.

I did 4500@11e6 and 3000@43e6 on it - no factors. Another 3000@43e6 in progress.

Can someone find a poly for this? If ECM doesn't hit, I can run SNFS next week.

VBCurtis · 2016-07-29, 07:09

Sure, I can get you a poly by the end of the weekend.
I'll run msieve-gpu to do so; if anyone else chooses to run, please use first coefficient above 1M.

RichD · 2016-07-29, 16:56

An average one from the 4M range to beat.

Sorry I'm late- I tied rich with my first run, so made a second run (which didn't help). Here are my two best:

Thanks guys for the polys. Ended up choosing VBCurtis first poly, though they were all similar in performance. Will start it in a day or two once resources free up. Will take a few weeks to fully fsctor.

unconnected · 2016-09-12, 08:44

Any progress here?

Yes, it's in LA and should be factored in two more days.

I've become spoiled by RyanP and his ability to chew through hundreds of iterations per day!

swellman · 2016-09-15, 13:38

I'm done. Series is at i1651 with a C149. Ran a bit of ECM to t35.

Somebody take it.
