Yep! As a min to 300k but plan so far to go beyond that. My other k I will drop at 300 k, testing is at 273k now with only 100 primes so far, I just might just drop that one early, what do you think.

 2006-01-11, 11:48 #61 Kosmaj     Nov 2003 E2616 Posts Grobie Cool, IMO it was a good decision to concentrate on this k. Only the gap between the last two primes is a little bit too large. But let's hope there will be many primes from now on. Just keep on going!
