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 1999 I started searching for large Cunningham chains and BiTwin primes and these two kinds of prime constellations are still my favorites. In 2000 I got in contact with Paul Jobling. He started developing NewPGen at that time and I was testing every version. We did some record searches together and later on also Michael Angel joined this team. I think these searches where also a reason for a lot of improvements done on NewPGen at that time. Since a few years I maintain a record list for Cunningham chains which can be found at http://users.cybercity.dk/~dsl522332/math/Cunningham_Chain_records.htm
