He spent the rest of his life studying number theory. He applied his expertise to finding factors of large numbers of the form an ± bn, such as Mersenne numbers 2p-1 and Fermat numbers 2(2^n)+1. His work is continued in the Cunningham project. Traditionally, number theory is that branch of pure mathematics concerned with the properties of integers and contains many open problems that are easily understood even by non-mathematicians. ...
