The average distance p(G) of a graph G is the average among the distances between all pairs of vertices in G. For n 2 2, the average Steiner n-distance ,4G) of a connected graph G is the average Steiner distance over all sets of n vertices in G. It is shown that for a connected weighted graph G, pu,

โฆ Synopsis
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.

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 cyclica
