Congratulations!

Great run Peter! Do you have a search limit on the remaining k's?

I'm waiting for a few subranges to finish that are running on slower machines. It will probably take until next week, then I can report results for all k's up to n=150k.

That's what we like, primes in bunches. Congrats Willem and Peter.
