According to [URL="http://www.15k.org/RPSotherRanges.html"]http://www.15k.org/RPSotherRanges.html[/URL], the range n=2,340,000-2,358,000 has already been tested (by Peter?).

Can someone confirm this?
Shall we skip this range or double check?

Not Peter, Dave did those tests, and also k=17 in the vicinity of n.

Dave, can you confirm?

Thomas, can you test only 2338-2340 and I'll release new files starting from 2358k shortly. Sorry about this!

And CONGRATS on that nice prime, 15*2^2323205-1, just a few digits shy of 700k digits!!
Ranked 71 among all known primes. Very nice! :cool:

The previous k=15 prime was found in December 2008, more than 2 and a half years ago!
