On 25 Jul 2009 1:11:48 UTC, PrimeGrid's Cullen Prime Search found another World Record Cullen Mega Prime: 6679881·26679881+1 The prime is 2,010,852 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 15th overall. It is the largest known Cullen prime and the largest found Mega Prime using LLR. This remarkable discovery comes less than 4 months after the last prime and is only the 16th known Cullen prime. Contact with PrimeGrid participant (spinner@) has not been returned. However, the participant is from Japan and is a member of Team 2ch. The prime was found using an Intel Xeon L5420 @ 2.50GHz with 6 GB RAM running Windows XP Professional. This computer took about 71 hours 58 minutes to complete the primality test. More details to come after contact is made.
