    • The G3 and G3MP2 approaches approximate very large QCISD-(T)/G3Large calculations by summing the energies from a series of smaller calculations and correction factors.

    • We note in passing a worrying point from the Liu/Guo data: the mean errors of the C-H and C-C bond energies increase as the basis set size increases. One expects the errors to decrease as the basis set size increases.
