Abstract: | The classes of the symmetric group ??N are identified by partitions of N. In this work an indexing scheme is presented which provides a dense enumeration of the classes of ??N. The method is based on a graphical representation of partitions of N, which also enables the determination of the class corresponding to a given number. © 1997 John Wiley & Sons, Inc.
