Taking the average gap between primes for k=15 and extrapolating, the
next prime would be around n=1.72M..right where we are LLRing at the moment.
No guarantees of course :wink:, but an interesting statistic.

Taking the maximum gap between primes and extrapolating with that would
put the next prime at n=3.8M :shock:

Taking 1742-1744.

3.8M is several years away and besides, this batch is sieved only to 3M!
Let's hope the next one appears much sooner...
