✦ Synopsis
Ab initio SCF !_CAO MO calculations, using gaussian-type functions and large basis sets with ncnr Hartree-Fock accuracy, have been carried out for the ground state of the permnnganate ion. The largest calculation performed ap plied 203 primitive gaussians.

Three-center approximations to the four-center integrals occurring in ab initio LCAO calculations are investigated. It is shown that significant gains in computer time can be obtained without sacrificing accuracy, if a suitable expansion basis is chosen.
