| Quote: | On 25 Dec 2011 13:31:28 UTC, PrimeGrid’s Sophie Germain Prime Search found World Record Twin Primes: 3756801695685*2^666669±1
The twin primes are 200,700 digits long, eclipsing the previous record of 100355 digits. They will enter Chris Caldwell's The Largest Known Primes Database ranked 1st for twins. This is PrimeGrid's third record twin.
The discovery was made by Timothy D. Winslow of the United States using an Intel Core i7 920 @ 2.67GHz with 8 GB RAM running Windows 7 Ultimate. This computer, using LLR, took 9 minutes and 21 seconds to complete the primality tests of both primes. Timothy is a member of The Knights Who Say Ni! team.
