On 08 Mar 2011 10:35:34 UTC, PrimeGrid's PRPNet found a Generalized Fermat mega prime: 40734^262144+1

The prime is 1,208,473 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 2nd for Generalized Fermat Primes and 26th overall.

The discovery was made by Senji Yamashita of Japan using an Intel Core 2 Quad Q9450 @ 2.66GHz with 2GB RAM, running Windows 7 Professional 64bit. This computer took 4 hours and 29 minutes to complete the primality test using pfgw64. Senji is a member of the PrimeSearchTeam.
