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 reflect on the primes currently on the list. (Many of the terms that are used here are explained on another page .)

My intention is to collect and display all known
Riesel-Primes of the form k*2^n-1 and some related
information on one page!
I'm collecting since 2007 and got information for about
8000 k-values with 160,000 primes and 3500 twins so
far.
Related pages for the Riesel-Problem, (Near-)Woodall-Primes
or the Liskovets-Gallot conjecture are also available;
furthermore many details about Prime-Search-Projects like
NPLB or RPS and their current search ranges and found
primes are available, too.
I'm updating almost every day this constantly increasing
Database.
Nov.2010:
I've included lists of Proth primes k*2^n+1 for k<10000
and Status pages (reservations/completions) for
k<1200.
Not yet all data available (like primes for k>10000 or
older status listings) are shown yet, this will follow the
next months.
Jan.2019:
A new Wiki for prime searching projects and related topics
can be found here .
