Paul Leyland
Paul Leyland is a British number theorist who has studied integer factorization and primality testing.
He has contributed to the factorization of RSA-129, RSA-140, and RSA-155, as well as potential factorial primes as large as 400! + 1. He has also studied Cunningham numbers, Cullen numbers, Woodall numbers, etc., and numbers of the form, which are now called Leyland numbers. He was involved with the NFSNet project to use distributed computing on the Internet from 2005 to 2008.
