N2 - For a planar graph H and a positive integer n we study the maximal number f = f(n, H), such that there exists a planar graph on n vertices containing f subgraphs isomorphic to H. We determine f(n, H) precisely if H is either a complete bipartite (planar) graph or a maximal planar graph without triangles that are not faces, and estimate f(n, H) for every maximal planar graph H.
