The symmetry reduction of icosahedral group has been carried out by means of projective operator method. The irreducible bases and matrices were tabulated for generators C 2 , C 3 and C 5 which would be sufficient for the implementation of ab initio or other computations in terms of symmetry‐adapted linear combinations of atomic orbitals. As an initial application, the borane dianion B 12 H 2‐ 12 with I h symmetry has been calculated with a flexible s, p set, (9s5p/4s) being contracted into [3s2p/2s]. The electron counting rule was then analyzed.
