For a positive integer d, the usual d-dimensional cube Q d is defined to be the graph (K 2 ) d , the Cartesian product of d copies of K 2 . We define the generalized cube Q(K k , d) to be the graph (K k ) d for positive integers d and k. We investigate the decomposition of the complete multipartite

Abstract
A cube factorization of the complete graph on n vertices, K~n~, is a 3‐factorization of K~n~ in which the components of each factor are cubes. We show that there exists a cube factorization of K~n~ if and only if n ≡ 16 (mod 24), thus providing a new family of uniform 3‐factorizations as well as a partial solution to an open problem posed by Kotzig in 1979. © 2004 Wiley Periodicals, Inc.

## Abstract Necessary conditions for the complete graph on __n__ vertices to have a decomposition into 5‐cubes are that 5 divides __n__ − 1 and 80 divides __n__(__n__ − 1)/2. These are known to be sufficient when __n__ is odd. We prove them also sufficient for __n__ even, thus completing the spectr
## Abstract For all integers __n__ ≥ 5, it is shown that the graph obtained from the __n__‐cycle by joining vertices at distance 2 has a 2‐factorization is which one 2‐factor is a Hamilton cycle, and the other is isomorphic to any given 2‐regular graph of order __n__. This result is used to prove s
## Abstract We show how to find a decomposition of the edge set of the complete graph into regular factors where the degree and edge‐connectivity of each factor is prescribed. © 2003 Wiley Periodicals, Inc. J Graph Theory 43: 132–136, 2003
## Abstract In this paper necessary and sufficient conditions are found for an edge‐colored graph __H__ to be the homomorphic image of a 2‐factorization of a complete multipartite graph __G__ in which each 2‐factor of __G__ has the same number of components as its corresponding color class in __H__
