for some of the largest systems on which a canonical CCSD(T) computation have been performed, the 16 and 17-molecule water cluster conformers with an aug-cc-pVTZ basis set. We compare our results to ORCA's implementation of DLPNO-CCSD(T), as well as a canonical MP2/CCSD(T) many-body expansion method. Finally, we benchmark our algorithm on a whole insulin chain (787 atoms), a system significantly beyond the reach of conventional coupled-cluster theory.
