"Three- and four-body nonadditivities in the uracil tetramer (in DNA-like geometry) and the GC step (in crystal geometry) were investigated at various levels of the wave-function theory: HF, MP2, MP3, L-CCD, CCSD and the CCSD(T). The HF and MP2 level do no provide reliable values for many-body terms due to improper description of monomer properties and dispersion energy nonadditivity. Benchmark CCSD(T) values are well reproduced on much cheaper MP3 and L-CCD levels. Inclusion of three-body terms is necessary for determination of optimal geometry parameters." .
