Earlier quoted context omitted.
I recommend re-reading the OC and the replies.
what is the OC? whose replies?? I think I gotta somehow get a better understanding of Mersenne and Eisenstein primes, but I don't like jumping through 'bureaucratic'-academic hoops to get things explained to me. it's only numbers, I have other things to do
I.e
999999999999995%5=0 999999999999992%2=0
Thus they are not prime numbers.
