## Abstract When calculating the correlation energy where the effect of higher than double excitations is included by means of many‐body Rayleigh–Schrödinger perturbation theory (MB‐RSPT) through fourth order the problem of cancellation of exclusion‐principle‐violating (EPV) diagrams arises. The ca
