Maximum G Edge-Packing is the problem of finding the maximum number of edge-disjoint isomorphic copies of a fixed guest graph G in a host graph H. This paper considers the cases where G and H are planar and G is cyclic. Recent work on the general problem is surveyed, inadequacies and limitations in these results are identified, and NP-completeness proofs for key cases are presented.
