Ryan is working a few numbers

C168_113_88
C192_115_79
C210_115_83
C221_113_100
C161_149_41

C192_115_79 Factored
 

Ryan found it via SNFS. [URL]http://factordb.com/index.php?id=1000000000044698139[/URL]

p94*p99, a nice split.

Ryan nailed another one, C210_115_83 by SNFS. See

C175_126_55
 

I would like to reserve C175_126_55 for SNFS. Results expected in early October.

Thanks.

I noticed that there's a neglected very easy SNFS number still sitting in the composite file. (145_80, diff. 176)

I'll do it overnight, unless someone has done it actually.

EDIT: done. p82 * p89. In FactorDB.

:shock:

According to my test sieving, that job would take me 4-5 weeks on my unremarkable i7. What kind of rig do you have? What poly did you use?

Nice job.

With the x[SUP]4[/SUP] - x[SUP]3[/SUP] + x[SUP]2[/SUP] - x +1 poly, it is a very easy job: 100-core hours (overnight with 12 cores).

There are no more missed reducibles in the list; I've played with some possible, hidden Aurifeuillians and haven't found any. There are some powers in the list like 128_125, many more 128s, a 64, a 32, some 121s and 125s, but they don't help. All reducibles (by 3, by 5, by 7) were done ages ago. I was surprised to see this one.
