The Combinatorial Compound of Permutation Matrix and Graphical Representation

考察了有向圈或圈并的r级合成图 ,分别确定了它们的所有圈长和圈数 ;

This paper investigates the r th Compound digraph of a directed cycle or the union of cycles.The lengths and numbers of all cycles in Compound digraph have been determined respectively.By graphical method,we characterize completely the combinatorial compound of permutation matrices.
