Re: Issue with fullfactor

Hi Jean-Luc,

To the best of my knowledge, fullfactor is outdated and was abandoned a few years ago.

There is a better substitute in using factordb.com for obtaining up-to-date known factors of many numbers of interest (including Cunningham).

I can share my GP scripts for accessing factordb.com if you are interested.

Regards,

Max

Hello,

I installed fullfactor as described in the doc, AFAIK.

Now, launching it with "\r fullfactor.gp", I'm getting this warning:

Any idea?

Pari/GP version is 2.16.0.
