First, we notice that neither the eb-MBE(2) nor the eb-MBE(3) are able to provide the correct energetic ordering of the isomers. While the energy-based three-body expansion Without the inclusion of an embedding potential, the isolated db-MBE does not provide useful results for the relative energies. However, if an embedding potential is included, already the one-body db-MBE(1) leads to a significant improvement compared to the eb-MBE(2) and eb-MBE(3). It groups the isomers correctly into a lower energy group (isomers 01, 02, 03, 04, 06, and 10) and a higher energy group (isomers 05, 07, 08, and 09), even though the ordering within these groups is not fully correct. This is remarkable, given that the db-MBE(1) uses only calculations for the embedded monomers.
