## Conjecture that States that Numbers 16^n-4^n+1 Are Either Primes Either Divisible by Poulet Numbers

**Authors:** Marius Coman

In this paper I conjecture that any number of the form 16^n – 4^n + 1, where n is positive integer, is either prime either divisible by a Poulet number (see the sequence A020520 in OEIS for the numbers of this form).
