Re: factor warning

[Max Alekseyev <maxale@gmail.com>]

Many of repuints are already factored - so it is a good idea to query
http://factordb.com for existing factorizations.

Btw, I have developed a gp function factordb() that gets
factorizations from factordb.com inside PARI/GP (under linux, using
perl and wget).
If anybody is interested, I can share.
Regards,
Max
