Narumi-Katayama index of phenylenes

The Narumi-Katayama topological indes S of a hydrocarbon is the product of vertex degrees of the respective molecular graph. If PH is a phenylene and HS is its hexagonal squeeze, then the respective Narumi-Katayama indices are related as S(PH) = 9h1 S(HS), where h is the number of hexagons of PH and...
