A topological index is a numerical quantity derived in an unambiguous manner from the structural graph of a molecule. One of the topics of continuing interest in structure-property studies is to arrive at simple correlations between the selected properties and the molecular structure. The hyper Wiener index is one of the recently conceived distance-based graph invariants, used as a structure-descriptor for predicting physico-chemical properties of organic compounds. The hyper Wiener index of a molecular graph is defined as one half of the sum of the distances and square distances between all (ordered) pairs of vertices of the graph. In this paper we obtain the hyper Wiener index of TUC4C8(R) nanotubes.
