Have you verified it?[/QUOTE]

For the last two days I've been trying. My connection was down. Just submitted.

Carlos

I meant: did you double check it? :smile:

Hi Carlos,

Congrats on a great prime!
The double check on Top-5000 will be over soon, but I trust in your hardware :smile:

That is really nice prime!
congratulations!
BTW I will never understand how primes are distributed over K: in relativy small range K5 give us 3 primes, and K15 , with much bigger sieve give us nothing :)
Oh those primes.... :smile:

Well done, Carlos! That's great prime.
Just a bit too small to hit the one million digits - what a pity...

Anyway, big congrats also from me.

My test:

[CODE]PFGW Version 3.7.5.64BIT.20130325.x86_Dev [GWNUM 27.8]

5*2^3264650-1 is 3-PRP! (19927.7290s+0.0022s)[/CODE]

Congrats for your prime, Carlos et al. :cool:

4051*2^1266809-1 (381352 digits)

... and congratulations Carlos.

Thank you all. Expecting two new core i7 to help the k=5 fun.

Carlos et al.

1293*2^1480046-1 (445542 digits)
1387*2^1390577-1 (418609 digits)

4069*2^1270119-1 (382348 digits)

I don't believe it - just below one million digits!

49*2^3309087-1 (996137 digits)
