Will certainly be listed soon on the Tony Forbes' List, meanwhile I checked myself the primality with an implementation of Mpz_Aprcl.

Please tell us which CPU was used and during how much time it ran.

Even though the Difficulty is not strictly 5% higher (it is 4.98%, but well it deserves to be rewarded...), you can claim a bounty of 2000 RIC by posting in this topic. viewtopic.php?f=17&t=6
