چکیده مقاله
A topological index is a numerical invariant of a chemical graph. In this paper, we apply the action of the symmetry group of a fullerenes molecule C60+12non the set of its chemical bonds to compute the PI index of C 60+12n . This is an efficient method that can be applied for other classes of fullerenes.
