Purpose
The goal of this project is to find Generalized Cullen primes for bases which have no known primes.
Status
The bases currently being searched by the project: 13, 29, 47, 49, 55, 69, 73, 101, 109, 121.
Found primes
Each of these finds was the first known Generalized Cullen prime in that base, eliminating that base from the search.
