In the management interface they are mentioned as

#156 30 Aug 2016, 13:39:42 UTC C272_136_105
#157 30 Aug 2016, 14:30:29 UTC C277_150_122

if that helps

Current status of the former:

Code:

linear algebra completed 39666384 of 42844005 dimensions (92.6%, ETA 90h47m)

so probably Friday morning, after several weeks on a 48-core machine.

With the quartic penalty, it wouldn't surprise me if the sieving for this number were faster by GNFS than SNFS. But that requires somebody taking time to find a polynomial, so all things considered it will probably be factored sooner by SNFS.

Even with the penalty, this number's a bit small, but right now we're a bit short on candidates and beggars can't be choosers. Enqueued.

RichD · 2016-11-22, 01:00

That was the smallest remaining composite on the server. The next one is a P55^5-1 (C177) but it will be days or weeks before many are ready for SNFS. More than a dozen are better than t50.

fivemack (loop (#_fork)) Feb 2006 Cambridge, England 3×2,141 Posts	In the management interface they are mentioned as #156 30 Aug 2016, 13:39:42 UTC C272_136_105 #157 30 Aug 2016, 14:30:29 UTC C277_150_122 if that helps Current status of the former: Code: linear algebra completed 39666384 of 42844005 dimensions (92.6%, ETA 90h47m) so probably Friday morning, after several weeks on a 48-core machine.
