A Note on Fowler-Manolopoulos Predictor of Fullerene Stability

Fowler-Manolopoulos criterion, that is defined as the second mo ment of the hexagon neighbor signature, is one of the most powerful predictors for fullerene stability. In this note, we present a relationship between Fowler-Manolopoulos predictor and another hexagonal para meter, which could give Fowler-Manolopoulos predictor a graphical explanation. This result can be regarded as an understanding of Fowler-Manolopoulos criterion.
