On 18 Jan 2012 21:13:24 UTC, PrimeGrid’s Generalized Fermat Prime Search found the mega prime: 525094^262144+1

The prime is 1,499,526 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 2nd for Generalized Fermat Primes and 24th overall.

The discovery was made by David Tomecko (KWSN Raw Data) of the United States using an NVIDIA GeForce GTX 570 in an Intel Core i7 980 @ 3.33GHz system with 24GB RAM, running Windows 7 Ultimate. This GPU took about 55 minutes 24 seconds to probable prime (PRP) test with GenefCUDA. David is a member of the The Knights Who Say Ni! team.

The PRP was verified on 19 Jan 2012 7:37:53 UTC, by Rick Reynolds (Rick Reynolds) of the United States. For more details, please see the official announcement.
