Allan Joseph Champneys Cunningham

(Redirected from A. J. C. Cunningham)
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 ($2^p-1$) and Fermat numbers ($2^{2^n}+1$) which have b = 1. His work is continued in the Cunningham project.
