Abstract
⺠We show the notion of generalized antisymmetrized product, generalized normal ordering (GNO) and cumulants. ⺠We show that all cumulants with rank greater than two have the antisymmetric property. ⺠Invoking an exponential parametrization of Ω in GNO, we formulate a compact Internally Contracted MRCC. ⺠The newly formulated Internally Contracted MRCC theory is manifestly size-extensive and orbital invariant.
