## Abstract We construct a new symmetric Hamilton cycle decomposition of the complete graph __K~n~__ for odd __n__β>β7. Β© 2003 Wiley Periodicals, Inc.
For all m = 0 (mod 41, for all n = 0 or 2 (mod m), and for all n = 1 (mod 2m) w e find an m-cycle decomposition of the line graph of the complete graph K,. In particular, this solves the existence problem when m is a power of two.
## Abstract A short proof is given of the impossibility of decomposing the complete graph on __n__ vertices into __n__β2 or fewer complete bipartite graphs.
In this paper it is proved that if a graph \(G\) has a decomposition into an even (resp., odd) number of Hamilton cycles, then \(L(G)\), the line graph of \(G\), has a decomposition into Hamilton cycles (resp., Hamilton cycles and a 2-factor). Further, we show that if \(G\) is a \(2 k\)-regular grap
## Abstract Graham and Pollak [3] proved that __n__ β1 is the minimum number of edgeβdisjoint complete bipartite subgraphs into which the edges of __K__~__n__~ can be decomposed. Using a linear algebraic technique, Tverberg [2] gives a different proof of that result. We apply his technique to show
