Abstract

Enumeration of chemical compounds has been accomplished by various methods. The Polya-Redfield theorem has been a standard method for combinatorial enumerations of graphs, polyhedra, chemical compounds, and so forth. In this paper by using the computer algebra system GAP we compute the number of isomers of an infinite class of nanohorns with C2 point group symmetry.

Keywords

Pólya's theorem, Cycle Index, Nanohorn.
