The m-connectivety and m-sum connectivity indices of G are defined as to be [wzór] and [wzór] where [wzór] runs over all paths of length m in G and di is the degree of vertex νi. In this paper, we give explicit formulas for the second-connectivity and second-sum-connectivity indices of an infinite class of Armchair Polyhex Nanotubes TUAC6[m,n].
