Abstract

A connected graph is said to be @?"1 if its path distance isometrically embeds into the space @?"1. Following the work of Deza, Grishukhin, Shtogrin, and others on polyhedral @?"1 graphs, we determine all finite closed polyhexes (trivalent surface graphs with hexagonal faces) that are @?"1.
