Paul Leyland

For the rugby league player, see Paul Leyland (rugby league).

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.[1] He was involved with the NFSNet project to use distributed computing on the Internet from 2005 to 2008.[2]

In 2002, he co-authored a paper with Samuel S. Wagstaff Jr. entitled "MPQS with three large primes" in the Proceedings of the Algorithmic Number Theory Symposium 2002. Since Wagstaff co-authored a paper with Paul Erdős, this means Leyland has an Erdős number of 2.
