The numbers of isomers in icosahedral fullerene C60 and Cg0 series have been enumerated by applying Polya's theorem and analysing symmetries of their molecular frameworks. Cycle indices have been deduced for chiral and achiral derivatives. Program operating with polydigital numbers have been applied to calculate numbers of isomeric derivatives up to C540.
