Hi danaj, fancy seeing you here! Thank you for this, will give it a work through when I get some time. You know why I am trying to do this program from Mersenneforum and it will need to be pretty efficient as I want to add more primes to get to an under-researched prime gap formula. Hard to beat your 1 liner, I think.
