I don't recommend the idea. It will take alot of computers to reach that goal. With only 4 users working on this project, it will take a long time to finish. edit: I will be moving to work on k=3^16 once I am done with my range. Jean, is it possible to speed up the PRP test for 3^16? It is a generalized fermat as well as k*2^n+1? Could a smaller FFT lenght be used? Last fiddled with by Citrix on 20070209 at 02:57

as I said I use this project as a extra cycle sink...and every little bit helps...I don't see this as all that pointless of a project and I think users could come someday in the future. we've got fewer than SOB, I don't mind just letting it sit in teh background of my comp and LLR....or sieve....but that's just me

Well, I've started NewPGen for k=18534, 1M < n < 2.5M (base 4), as there are the fewest tests left for this k.
I haven't done any work for the other k's so far. But I think we should be ready for a combined sieve effort with sr2sieve once we reach the limit of the current candidate files. Geoff: Is there a lower limit for p values in sr2sieve? So far, I've sieved to p=40M.

Great (pun not intended)!
So we could prepare the sieving within the next weeks.

I'm interested in helping this project, just not in the immediate(within the next week or so) future.
Has anyone thought about setting up an LLR server for these numbers? If you did, it would probably be a good idea to set up the numbers as k*2^n+1 , rather than k*4^n+1 . Wouldn't want to get errors from people having their computer set up improperly. :)

Not worth it with just 4 ks remaining. And llr handles 4^n as 2^m... that wouldnt be a problem at all.

It is not quite exact ; the LLRNET server takes into account the header of the Newpgen file, and sends the info to the client, so, the base info is not lost.
