According to http://www.15k.org/RPSotherRanges.html, the range n=2,340,0002,358,000 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 23382340 and I'll release new files starting from 2358k shortly. Sorry about this!

And CONGRATS on that nice prime, 15*2^23232051, just a few digits shy of 700k digits!!
Ranked 71 among all known primes. Very nice! The previous k=15 prime was found in December 2008, more than 2 and a half years ago!
