.... PR91, Sta92, Wes93] and (7) listing the elements of a Coxeter group so that successive elements differ by a reflection [CSW89] Gray codes have found applications in such diverse areas as circuit testing [RC81] signal encoding [Lud81] ordering of documents on shelves [Los92] data compression [Ric86], statistics [DH94] graphics and image processing [ASD90] processor allocation in the hypercube [CS90] hashing [Fal88] computing the permanent [NW78] information storage and retrieval [CCC92] and puzzles, such as the Chinese Rings and Towers of Hanoi [Gar72] In recent variations on ....
....of binary Gray codes to m ary Gray codes. It was shown in [JWW80] using a generalization of the binary reflected Gray code scheme, that it is always possible to list the Cartesian product of finite sets so that successive elements differ only in one coordinate. A similar result is obtained in [Ric86] where each coordinate i is allowed to assume values in some fixed range 0; N i Gamma 1. Squire generalizes results on clean words to m ary Gray codes [Squ96] but leaves open the case when m is odd. Another listing problem for binary numbers, posed by Doug West, involves a change in the ....

....the binary reflected Gray code [Gra] which is a list of all n bit binary strings in which each string differs from its successor in exactly one bit. By applying the binary Gray code, a variety of problems have been solved and the complexities of the solutions to other problems have been improved [Gar, ChLeDu, ChChCh, Los, Ric]. There are many examples of combinatorial families for which Gray codes are known, including permutations [Joh, Tro] combinations [BuWi, NiWi, Rus1] compositions [Kli] set partitions [Kay] integer partitions [Sav, RaSaWe] binary trees [RuPr, Luc, LuRoRu] and linear extensions [PrRu1, PrRu2, ....
