François Morain


A titan, as defined by Samuel Yates, is anyone who has found a titanic prime. This page provides data on those that have found these primes. The data below only reflects on the primes currently on the list. (Many of the terms that are used here are explained on another page.)

Franĉois Morain is an active researcher in the areas of computational number theory and cryptography. He found his titanic primes using his version of the ECPP algorithm (see also [AM93]). Morain holds the record for the largest known prime without a "special form."

Surname: Morain (used for alphabetizing and in codes).
Unverified primes are omitted from counts and lists until verification completed.
