Did any ECM get sent to yoyo?
This could be a stretch (in a good way) on the 15e queue, same size as the currently sieving number in the queue, or we could do a short teamCADO sieve on it. Should be 2025 threadyears of sieving on CADO. Let's get the ECM finished while we decide?

Yes, someone queued AS 276 for 10,000 curves @B1=260e6. It should start processing in 12 weeks. It will take some months to run ECM to the t65 level, but your suggestion about sieving could be fun. We can collectively decide as ECM draws to a close.

0.31*size is a bit under 62 digits of ECM. How about a traditional T60, and a T60 worth of B1=850M curves? CADO is growing faster each year, which would lead one to spend a bit less effort on ECM than historical norms might suggest.

If we get to 1t60 as above, how many curves are then required @B1=850e6 to reach another t60? 24,000?

ecm v (on v. 7.0.1) says 16400 curves at 850M is a T60.
So, how about 16,000?

Ok, 16,000 curves @B1=850e6 if necessary.

You might want to hold off with (or abandon) the ECM; I've managed to get the c198 blocker to linear algebra.

I’ve asked Yoyo to kill this queued ECM job. Happy factoring!
Eta: Yoyo has removed this composite from the queue. Last fiddled with by swellman on 20200116 at 19:14
