Should I lose or forget to post these factorizations to FDB once it gets back up and running.

Code:

FDB is running now, at http://factordb.com/. Are you trying to access factorization.ath.cx, that still points to the old server at the old IP address and just says

Moving over to a new, more energy efficient server. Will be back in ~2 hours.

What do you mean? FactorDB is up and running.

From what I have seen it has been up and down like a yoyo the last few days.

RichD · 2016-12-05, 19:17

I’ve recently learned the first 500-600 numbers in the t800 file have 10,000 @ B1=43M, which means nearly all of those are ready for NFS. I believe it is sorted by size (remaining composite) so anything < C184 is game for GNFS/SNFS.

Someone needed a “burn in” of a new cluster and Pascal was at the right spot at the right time. Many factors fell out but the remaining ones are still in the file.

The smaller ones can be done in under a day even if it requires GNFS poly selection.

RichD · 2016-12-05, 19:56

I have identified 6 of the form P45^5-1. I will work on those in the coming days.

I also identified some other groups suitable for SNFS.

P30^7-1

Code:

808731825335254769723204529427^7-1
178613433446882840962083832831^7-1

409826970748952032136713489831^7-1

Don’t forget you can use degree halving on the next two groups.
P19^11-1

Code:

3191686493279737051^11-1
9224843685451579741^11-1

1276649964690308261^11-1
2281074882720528877^11-1

P16^13-1

Code:

1146504157422163^13-1
5231536691351629^13-1
6961384333116919^13-1

Thanks to chris2be8 which picked off a couple P30^7-1 numbers and a secret Santa shopper which picked off a few GNFS ones, there are only about four GNFS numbers that be be completed in under a day. Most SNFS number are in the 1.5 day range (assuming a 4 core machine). Hopefully I will get a list of P46^5-1 numbers posted tomorrow for the easiest SNFS jobs.

RichD · 2016-12-17, 00:37

A few more (relatively) easy ones.

P46^5-1

Pascal (or somebody) removes the factored numbers from the t-files on a somewhat timely basis. That said, I am providing an update to two of the above groups plus adding the next size 13ers. Since someone likes working those.
