The average n-distance of a connected graph G, p,,(G), is the average of the Steiner distances of all n-sets of vertices of G. In this paper, we give bounds on pn for two-connected graphs and for k-chromatic graphs. Moreover, we show that pn(G) does not depend on the n-diameter of G.

✦ Synopsis
We consider classes of cubic polyhedral graphs whose non-q-gonal faces are adjacent to qgonal faces only. Structural properties of some classes of such graphs are described. For q 5 we show that all the graphs in this class are cyclically 4-edge-connected. Some cyclically 4edge-connected and cyclically 5-edge-connected non-Hamiltonian members from this class are presented.
