چکیده مقاله :

The Wiener index of a graph G is defined as W(G) = ... where V (G) is the setof all vertices of G and for i,j in V (G), d(i,j) is the minimum distance between i and j. Ashrafiand yousefi (see A. R. Ashrafi and S. Yousefi, Computing the Wiener Index of a TUC4C8(S)Nanotorus, MATCH Commun. Math. Comput. Chem., 57(2)(2007), 403-410) computed theWiener index of TUC4C8(S) Nanotorus. In this paper we use a new method to compute theWiener index of these Nanotorus.
