On 28 Feb 2012, PrimeGrid’s Primorial Prime Search, through PRPNet, has found a world record primorial prime: 1098133#-1

The prime is 476,311 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Primorial primes and 253rd overall.

The discovery was made by James P. Burt (jpaul) of the Cayman Islands using an AMD Phenom 9750 Quad-Core @ 2.4GHz with 4 GB RAM running Windows 7 Professional x64. James is a member of the Aggie_The_Pew team.

This is only the 20th known p#-1 Primorial prime and the 2nd discovered in the last 20 years. For more details, please see the official announcement.

Where is the next +1 primorial? PrimeGrid found two -1 primorials. No new +1 primorials have been found in over a decade. Maybe 2012 will be the year to find the next one.

I just realized that in one week that three different PRPNet projects found record setting primes. 121, 27, and now Primorial.

Which one will be next? SG? GFN? CW? Factorial?

I would bet GFP or TRP. That's where the action is.
