  Abstract:  Omega polynomial  Ω(G,x) is defined on opposite edge strips ops which are quasi orthogonal cuts qoc in a graph G=G(V,E), with the meaning the transitivity relation is not necessarily obeyed. The first and second derivatives, in x=1, of Omega polynomial provide the Cluj-Ilmenau CI index. The polynomial provides an appropriate topological description of infinite crystal-like networks. Close formulas for the number of atoms, Omega polynomial and CI index are derived for a lattice designed by using operations on maps/networks.

Keywords: graphene, CorSu network, Omega polynomial.
