Enumeration of Polyhex Hydrocarbons to h: 17

Abstract

This paper describes a rather efficient algorithm that enumerates nonisomorphic geometrically planar, simply connected polyhexes (hexagonal systems). It has been implemented in Modula-2 and used to determine andclassifythepertinentsystemswithli <lThexagons. Theresultforh:17,vi2., 1151594643, isnew
