After extensive experimentation, we have determined that T STRONG SCALE QUADS = 2, and T WEAK SCALE QUADS = 10 provides sufficient accuracy (less than 1 µHartree deviation for the iterative (Q) contribution to the energy). Next, the amplitudes are iteratively updated in the lower rank QNO basis (Algorithm 5), with the storage requirements of Γ abcd ijkl and t abcd ijkl being, on average, lower than the memory requirements of the preceding DLPNO-CCSDT computation. For clarity, "nonunique LMO quadruplets", as presented in Algorithm 5, are defined as the set of all quadruplets (i, j, k, l), such that when the tuple is listed in ascending
