A new graphene pattern, called CorSu, was designed and the energy of some small fragments of the lattice, functionalized by groups containing oxygen, carbon, nitrogen and phosphorus, was evaluated at the level of semiempirical method PM3. The topology of the network is described in terms of Omega counting polynomial. Close formulas for calculating the polynomial and the Cluj-Ilmenau index derived from this polynomial are given.
