Taking this one for NFS@Home's 14e.

Next blocker is C153@i1629 which resists 3000@43e6 from me.

I'll factor it.

It's factored now.

What's the status of this C149 or the C180 of 3366?

unconnected 2016-06-09 11:55

C149 is ready for nfs, C180 survived 3000@43e6 so far.

Dubslow 2016-06-10 02:08

I'll NFS the C149 here.

Dubslow 2016-06-19 01:35

I'm slowly working towards t45 on i1634 C167.

Dubslow 2016-06-23 02:40

Near completion of the t50, a p50 popped out; NFS on the remainder revealed a p48 and p70. It was a bit unlucky, though possibly the two digits of NFS time saved is more than the average longer amount of work to find the p50.

In either case, i1636 has a C180 at t45, though it'll likely be the better part of a week for me to complete a t50.

Dubslow 2016-06-29 03:53

Someone else has also found the P48, though I'm past that and currently NFSing a C136 (should be less than 10 hours before that completes).

I will be working every number through either fully factoring it myself and moving on, or seeing ECM and polyselect through to NFS@Home, or until such time as I post that I have given up on the number.

Dubslow 2016-06-29 21:49

Or not. Someone with more resources is pushing the sequence past me.
