The verification just finished. M42643801 is the 47th known Mersenne prime! It is not quite as big as the Mersenne prime found last August. Percentage-wise M42643801 and M43112609 is the shortest gap between Mersenne primes.
The prime was found by Odd Magnar Strindmo in Norway. He has been a GIMPS participant for over 12 years. Congratulations to Odd and all the other GIMPS contributors that made this possible. _______________________________________________ Prime mailing list Prime@hogranch.com http://hogranch.com/mailman/listinfo/prime
