Extrapolated DLPNO errors for these systems are presented in Fig. . For (C 96 H 24 ) 2 , the L/N MP2 scheme performs affords an error of almost 5 kcal/mol and even larger errors are incurred using the (L/N) CCSD(T) and (N/T) CCSD(T) schemes that employ CCSD(T) thresholds. For this largest system, (N/T) MP2 extrapolation a MP2 thresholds (see Table ).
