A Family of Counter Examples to an Approach to Graph Isomorphism

Abstract

We give a family of counter examples showing that the two sequences of polytopes Φn,n\Phi_{n,n} and Ψn,n\Psi_{n,n} are different. These polytopes were defined recently by S. Friedland in an attempt at a polynomial time algorithm for graph isomorphism.
