The numbers in VHL are getting no work due to the workers running aliquot sequences.

might be a good idea
i have been thinking ever since msieve got it's own subforum that a ggnfs subforum would be helpful

I think a 'factoring database announcements' thread and 'factoring database issues' thread would be useful, and I would then be tempted to delete this thread: it is very large and full of one-line back-and-forths which do not necessarily need to be archived for the ages.

I'm not sure a GGNFS sub-forum is terribly useful, the discussion is spread out over several threads in the Factoring forum most of which have reasonably useful titles - generally people have reported non-trivial bugs in threads with relevant titles in which the bug-fixing work can be carried out.

The factoring database is a bit different because people seem to report a lot of trivial bugs and 'non-bug issues' in its single thread.

I have updatet a lot of Cunningham Numbers 2^n+1 from 1200-1700 in Syd`s Database. The new factors are from this site http://www.euronet.nl/users/bota/medium-p-even4k.txt
The new factors are from May 2009

I just noticed an excellent enhancement that Syd appears to have just made: Whenever I complete an Aliquot sequence, the next sequence automatically factors to 1e7 (instead of just 2000). That saves me a click and time. Over the many clicks that I make, it saves me a LOT of time!

Thanks Syd!

You can find three files at http://www.euronet.nl/users/bota/medium-p.htm , amongst which the one referred to above. Richard Brent sometimes includes my factors in his updates, but I don't know whether he does this very systematically...

Thanks for the Link and for Information.
I have updatet now all factors from http://www.euronet.nl/users/bota/medium-p-even4k.txt . Next table updates in the DB are coming the next days.

I have updatet the Database with factors from this Site
http://www.euronet.nl/users/bota/medium-p-odd.txt
In this List is a wrong factor for 2^1337+1 !!
The factor 10051655137687975879415699639722354859 is only a factor from 2^1237+1 and not 2^1337+1 .
I have send a Mail to Richard P. Brent - hope he an correct this fault.

Richard was so kind to forward the message to me. I add the factors manually to the list, and this is bound to go wrong once in a while

. The error should be corrected now!

Quick question: how exactly does the "add sequence to workers" button work? I tried it earlier today on a relatively small sequence (~20 digits, if memory serves), and it ran for a few seconds, but then disappeared from the worker queue with absolutely no additions to the sequence. Am I misunderstanding something about this?
