Purpose
The goal of this project is to find Generalized Cullen primes of the form n•bn+1 for bases b which have no known primes.
Status
The bases currently being searched by the project:
Found primes
Each of these finds was the first known Generalized Cullen prime in that base, eliminating that base from the search.
