On 04 Oct 2010, 15:01:15 UTC, PrimeGrid’s PRPNet found the largest known Factorial prime: 94550!-1

The prime is 429,390 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Factorial primes and 155th overall.

The discovery was made by Dmitry Domanov of Russia using an Intel Intel Xeon E5310 @ 1.60GHz with 4GB RAM, running 32 bit Windows 2003 Server. This computer took 24 hours and 19 minutes to complete the prime test using pfgw. Dmitry is a member of Team Russia.
