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.)

In 1963 Gillies discovered the three Mersenne primes 2¹¹²¹³-1, 2⁹⁹⁴¹-1 and 2⁹⁶⁸⁹-1 [Gillies64] during the checkout of the Illiac-II supercomputer for which he designed the control pipelining. The primality testing algorithm exercised nearly every circuit in the Illiac-II. Gillies died of a rare virus in 1975, at age 47.

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