It appears that the first 128 terms of this sequence constitute all of the primitive elements of GF(256) if each term is the exponent of the minimum primitive element for the irreducible polynomial splitting GF(2). For example, when GF(2) is split by F(x) = x^8 + x^4 + x^3 + x + 1, the minimum primitive element is a = x + 1. Then the primitive elements of the finite field are a^1, a^2, a^4, a^7, ... - Cody Planteen, Jul 27 2019
