I'm interested in mathematics at a recreational level and Mersenne numbers in particular. I have contributed to the Great Internet Mersenne Prime Search (mersenne.org) by doing several thousand Lucas-Lehmer tests, have discovered numerous factors of Mersenne numbers, and have found PRP cofactors of various Mersenne numbers including 2^4834891-1 and 2^7080247-1.
