%C Primes that behave like Shannon entropy power white noise with n=1.
%C Since (2*Pi/E) is a transcendental irrational, this function is a kind of irrational rotation related function, that is: Mod[(2*Pi/E)*n,1] is an irrational rotation and these numbers are Beatty in type such that: Beatty number+ irrational rotation =n Of my experiments in white noise entropy powers N=2 gives the most primes
