چکیده

where m is the number of edges, μ is the cyclomatic number of G, d(u) is the
sum of distances between vertex u and all of the vertices of G, and the summation
goes over all edges from the edge set E(G). In this paper we obtain a
method for calculating the Balaban index of nanotubes which have square and
octagon structure and denoted by C4C8(S) nanotubes.
