Thread: Generalized Mersenne Primes View Single Post
 2012-10-27, 16:04 #1 Unregistered   23·17·73 Posts Generalized Mersenne Primes I believe that I remember a theorem having to do with Generalized Mersenne primes of the form: (a^n+b^n)/(a+b). The theorem states that if (a^n+b^n)/(a+b) is prime, then n must also be prime. Does anyone know a reference that has a proof of this? Thanks.
