On 11 June 2011, PrimeGrid’s PRPNet found the largest known Factorial prime: 110059!+1

The prime is 507,082 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Factorial primes and 130th overall.

The discovery was made by Peter Doggart (Hammeh) of the United Kingdom using an AMD Phenom 9600 X4 @ 2.3GHz with 3GB RAM, running 32 bit Windows 7. This computer took just under 57 hours and 46 minutes to complete the primality test using pfgw. Peter is a member of the PrimeSearchTeam.

For more details, please see the official announcement.

Just had a wee look, seems like my test is still going to finish ahead of the Prime Pages but I guess we will just have to wait and see!
