Conjecture on a Subset of Woodall Numbers Divisible by Poulet Numbers

Authors: Marius Coman

The Woodall numbers are defined by the formula W(n) = n*2^n – 1 (see the sequence A003261 in OEIS). In this paper I conjecture that any Woodall number of the form 2^k*2^(2^k) – 1, where k ≥ 3, is either prime either divisible by a Poulet number.
