Absgtract:The graph decomposition problem is well known. We say a subgraph G divides K m if the edges of K m can be partitioned into copies of G. Such a partition is called a G-decomposition or G-design. The graph multidecomposition problem is a variation of the above. By a graph-pair of order t, we mean two non-isomorphic graphs G and H on t non-isolated vertices for which GHK t for some integer t4. Given a graph-pair (G,H), if the edges of K m can be partitioned into copies of G and H with at least one copy of G and one copy of H, we say (G,H) divides K m . We will refer to this partition as a (G,H)-multidecomposition. In this paper, we consider the existence of multidecompositions for several graph-pairs. For the pairs (G,H) which satisfy GHK 4 or K 5, we completely determine the values of m for which K m admits a (G,H)-multidecomposition. When K m does not admit a (G,H)-multidecomposition, we instead find a maximum multipacking and a minimum multicovering. A multidesign is a multidecomposition, a maximum multipacking, or a minimum multicovering.
