In this paper we give a GAP program for computing the Szeged and the PI indices of any graph. Also we compute the Szeged and PI indices of VC5C7[p,q] and HC5C7[p,q] nanotubes by this program.
Keywords: Szeged index; PI-index; nanotubes; Gap programming. Szeged index; PI-index; nanotubes; Gap programming.
