# Conjectures 'R Us

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.)

Descriptive Data: (report abuse)
 Our project aims to prove many of the Riesel and Sierpinski conjectures for bases 2 thru 1030 that are not currently being worked on by other projects or efforts. Definition: For every base (b) for the forms k*b^n+1 and k*b^n-1, there is a k-value for each form that has been conjectured to be the lowest 'Sierpinski value' (+1 form) or 'Riesel value' (-1) that is composite for all values of n >= 1. Conjectures must have a finite covering set. k-values are not considered in instances where all n's are covered by one trivial factor, all n's are covered by algebraic factors or by a combination of algebraic factors and trivial factor(s), or make Generalized Fermat #'s. We also have a BOINC effort named SRBase that helps greatly in working on the project. Details can be found at: https://srbase.my-firewall.org/sr5/

Unverified primes are omitted from counts and lists until verification completed.
