Cycle decompositions of crowns

Abstract For an integer n⩾3, the crown Sn0 is defined to be the graph with vertex set {x0,x1,…,xn−1,y0,y1,…,yn−1} and edge set {x i y j : 0⩽i,j⩽n−1, i≠j} . In this paper we give some sufficient conditions for the edge decomposition of the crown into isomorphic cycles.
