	Article:	COUNTING NUMBERS OF PERMUTATIONAL ISOMERS OF AN INFINITE FAMILY OF FULLERENES. Authors: MARYAM JALALI, MODJTABA GHORBANI.


	Abstract: Hetero-fullerenes are fullerene molecules in which one or more carbon atoms are replaced by hetero-atoms such as boron or nitrogen, whose formation is a kind of “on-ball” doping of the fullerene cage. In this paper, the numbers of all C_40n-kX_k hetero-fullerenes are computed, where C_40n is an infinite family of fullerenes. We apply the computer algebra system GAP to compute the number of permutational isomers of hetero-fullerenes of the C₈₀ fullerene with D₂₀ point group symmetry. Keywords: Fullerene, Hetero-fullerene, Cycle Index, Permutation Group.
