Abstract

The hyper Wiener index of a molecular graph is defined as one half of the sum of the distances and square distances between all (unordered) pairs of vertices of the graph. In this paper we find an exact formula for calculation of the hyper Wiener index of nanotubes which have square and octagon structure and denoted by C4C8(S) nanotubes.
