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

unconnected · 2016-06-07, 23:05

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

I'll factor it.

unconnected · 2016-06-08, 07:46

It's factored now.

Code:

Using B1=43000000, B2=240490660426, polynomial Dickson(12), sigma=3169275245
Step 1 took 204480ms
Step 2 took 63339ms
********** Factor found in step 2: 113620712594484464788316394064963357489161663400363
Found probable prime factor of 51 digits: 113620712594484464788316394064963357489161663400363

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.
