A note on the entropy of repetitive sequences of symmetry group permutations

Abstract

The paper makes the observation that all orders of information entropy are equal in signals composed of repeating units of distinct symbols where the units can be classified as a member of a symmetry group. This leads to an improved metric for measuring the information content of higher order entropies in data such as text, signals, or genetics and another measure of similarity to compare the incremental information content across entropy orders when comparing data of different sizes and symbol sets or when comparing entire sequences.
