Zusammenfassung:Chemical indices of graphs have been studied intensively in the recent years and some generalizations of old indices are very useful in chemical research. In this paper we study Graovac-Pisanski index (sometimes known as modified Wiener index) which is denoted by Ŵ. We derive recursive and closed formula for the Graovac-Pisanski index of the classical Sierpiński graphs (i.e., the Sierpiński graphs with base 3, S3n).
