finding unknown primes can also be pretty lucrative

I wonder if your system would help find some of these...

Probably just a typo, but should this be Circle 71, Ray1?


Darn !!! Yes, it IS a typo and you're correct ... just goes to show that no matter how many times I proof read before posting, errors still sneak through

Good catch, MickC

Believe me, the thought had definitely crossed my mind !

Obviously you can extend ANY of the 8 rays indefinitely and be GUARANTEED that they will contain primes in EXCESS of 10,000,000 or 100,000,000 or even 1,000,000,000 digits ... that's the easy part.

The hard part comes when you select what looks like a promising prime number candidate from one of those rays and then have to PROVE DEFINITIVELY that is in fact a prime.

But I'll certainly be looking further into this aspect ... after all, SOMEONE has to eventually win one or more of those prizes !
