Purpose

The goal of this project is to find Generalized Cullen primes of the form nbn+1 for bases b which have no known primes.

Status

  • Current status
  • Multi Reservation 17: The current test size is 6,595,852 digits as of 2024-09-26.
  • Important note: Tests are handed out by size of test instead of n-value. The above multi-reservation is set to the current n-value of the largest base of the project. Calculations must be made on each base so that its corresponding n-value is shown correctly.

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.
