Nice. :smile:

469*2^1012299-1 is prime. :smile:

Odicin has two top-5000 primes from port 9000 that need to be reported.

I have sent an Email to his last known Email address, that is the one that the server sends notifications to.

Apparently they are now coming in pairs then:
471*2^1017306-1
549*2^1021391-1
are prime. :smile:

441*2^1021669-1 is prime.

407*2^1025072-1 is prime.
