The Great Internet Mersenne Prime Search has once again had a sucess. On December 6, GIMPS announced that Michael Cameron, a 20-year-old GIMPS volunteer, discovered the 39th (and largest to date) Mersenne prime. Cameron used his PC and software by George Woltman and Entropia, Inc. to conduct his part of the search. The new Mersenne prime is 213466917 - 1. For more information on GIMPS and the newly discovered prime, visit http://www.mersenne.org/13466917.htm or http://www.utm.edu/research/primes/notes/13466917/. Richard Crandall has once again put together a poster containing the complete printout of the over four million digits in the new prime.
