On Automorphism Groups of Networks

arXiv:0705.3215 · doi:10.1016/j.dam.2008.04.008

Abstract

We consider the size and structure of the automorphism groups of a variety of empirical `real-world' networks and find that, in contrast to classical random graph models, many real-world networks are richly symmetric. We relate automorphism group structure to network topology and discuss generic forms of symmetry and their origin in real-world networks.
