Yoyo is finishing up 48,000 curves @B1=850e6. I consider ECM complete.

Here's a poly:

Since this is a record score, I'll guess we can think about sieving it or sending it to NFS@home?

swellman · 2021-10-04, 20:47

Small world - I was just reviewing this thread and realized the same thing.

The f_small siever can handle a job of this size.

swellman · 2022-01-02, 23:22

NFS@Home sieved this and Greg ran the LA.

I advanced it up to i1695 (c185) but now it’s free to anyone that wants it. Good luck!

Hey, that's only because it's Jan 5

Handing off this sequence for now at i1704, which has a c175.

bur · 2022-01-20, 17:25

Just for the record, there was probably a lot of ECM work done already?

On the c175 at i1704, I did 19K curves at B1=26e7.
