public class SignatureQuotientGraph
extends signature.AbstractQuotientGraph

A signature quotient graph has a vertex for every signature symmetry class and an edge for each bond in the molecule between atoms in their class. So a structure where all the atoms are in the same symmetry class will have a quotient graph with one vertex and one loop edge. At the other extreme, a structure where every atom is in a different class will have a quotient graph the same as the molecule.
