Abstract:In this paper we, present some MATLAB and GAP programs and use them to find the automorphism group of the Euclidean graph of the C80 fullerence with connectivity and geometry of I h symmetry point group. It is proved that this group has order 120 and is isomorphic to I h ≊Z2×A5, where Z2 is, a cyclic group of order 2 and A5 is the alternating group on five symbols.
Keywords:Fullerene                      Euclidean graph                      symmetry
