OK, I will start looking also for GQ, but then it will probably take me ~4 months to fill the gaps

Congratulations to Cruelty on the new record Gaussian Mersenne norm! It's only the 12th norm with more than 1000 digits, and the first megabit one. :surprised

And the first one found using LLR!

BTW, I'd like to suggest that posts about this find (and GM) be moved to a new thread.

Question

I'm just curious if there is any feasible way to prove GQ(p) prime for p>10^6?

What is the status of the Fermat Numbers factoring project? It seems the website http://www.fermatsearch.org/ had it's last update back in 2005.

Also, the program I downloaded had the option to attach to a server. Was there a central server at some point?

You can find known factorizations of Fermat numbers at http://www.prothsearch.net/fermat.html . The last one was found on August.

Um, yeah, I've seen that. I mean is the search ongoing and how would I join?

Thanks, Alperton, I guess I should have looked harder.

Sorry about that.

I did some stuff for the Fermat search project involving trying to find "small" primes of the form k*2^n+1. They sent me the username and password, but I forgot it. But, from what I think I remember about the username and password they supplied, it was a generic combination that was applied to everybody. Possibly implemented to prevent hackers.

Since I'm already a user there, and assuming I'm right about the generic username password, could someone please PM it to me?
