The symmetric group approach SGA is used to derive formulas for the Hamiltonian matrix elements between perturbatively generated, highly contracted Ž . configuration state functions CSF . The first-order Møller᎐Plesset, Epstein᎐Nesbet, and Krylov corrections are examples of such CSFs. They have been

## Abstract Addition and subtraction operators defined on some subspaces of the full CI space are introduced. It is shown that the effect of these operators on Löwdin many‐electron wave functions consists in adding or removing an electron without destroying spin symmetry. Upward and downward recurr
