It is proved that any edge of a Pconnected non-planar graph G of order a t least 6 lies in a subdivision of K3,3 in G. For any 3-connected non-planar graph G of order a t least 6 we show that G contains at most four edges which belong to no subdivisions of K3,3 in G.

## Abstract We investigate the behavior of the function __f__ = __f(n, k, e)__ defined as the smallest integer with the following property: If in a graph on __n__ vertices, the numbers of edges in any two induced subgraphs on __k__ vertices differ by at most __e__, then the graph or its complement

G be a subgraph of the Cartesian product Hamming graph (Kp)r with n vertices. Then the number of edges of G is at most (1/2)(p -1) log, n, with equality holding if and only G is isomorphic to (Kp)s for some s 5 r.
