Abstract
Given a family of multigraphs without isolated vertices, a multigraph M is called -decomposable if M is an edge disjoint union of multigraphs each of which is isomorphic to a member of . We present necessary and sufficient conditions for the existence of such decompositions if comprises two multigraphs from the set consisting of a 2-cycle, a 2-matching and a path with two edges.
