Neo,

It is not necessary to report primes that are not in the top-5000 of all time in this thread. We don't have any formal place to report these smaller primes. We just accumulate them and add them to the applicable post and show who found them as we go along.

I have changed the title of this thread to add "top-5000" to the verbiage. Sorry about any confusion.


Gary

Finally--I've at long last found a prime on the 7th Drive! (It may not seem like a long time just considering the 7th Drive, but when you count all the time I spent on the 5th and 6th trying to find a prime...yeah, it's been a while. )

921*2^866334-1 is prime!

This is my first top-5000-worthy NPLB prime that I've found since June 2009! (I reported one in September 2010 but that was actually one of Gary's that he "gave" me because he lost a bet.)



Okay, that's enough celebration...after all, it's just another 7th Drive prime, one of which is not supposed to be too hard to obtain.
