The decomposition of representations of compact classical Lie groups into representations of finite sub-groups is discussed. AMATHEMATICApackage is presented that can be used to compute these branching rules using the Weyl character formula. For some low order finite groups including A4and (27)general analytical formulas are presented for the branching rules of arbitrary representations of their smallest Lie super-groups.
