Starting with size-consistency, we first consider the requirements of each tensor regarding spatial proximity of their respective orbitals. ⟨pq||rs⟩, for example, is large if the orbital pairs p, r and q, s or the orbital pairs p, s and q, r are relatively close. Therefore, assuming that ⟨pq||rs⟩ possesses significant magnitude implies either of these schemes of proximity. An analogous scheme holds for the amplitudes, where either i, a and j, b or i, b and j, a must be close. Lastly, the elements of a fock matrix are also only significant in magnitude if their orbitals are in relative proximity. This notion of two orbitals being close can be rigorously formulated as the limit of infinite distance. Taking the first example, it holds that: Denoting each contribution to the regulariser as a diagram, we can describe these implied proximities as a walk across Fermion lines. Two details are important here: First, since we only consider ERIs, amplitudes and Fock matrices, all nodes have an equal number of ingoing and outgoing Fermion lines. It is therefore always possible to leave a node once entered. Second, the aforementioned pairs of proximity have the straightforward diagrammatic interpretation that we only need to consider walks which visit each Fermion line exactly once. To better illustrate this, consider an abstract ERI ⟨pq||rs⟩. If we arrive to this ERI from the p Fermion line, we can choose to leave the ERI either via r or via s. In the former case, we thus automatically imply that p, r and q, s are close, while it is p, s and q, r in the latter case. Thus, if we enter the ERI from an unused Fermion line for the second time, the previous choice of proximity pairing already determines that we have to leave the ERI through its last unused Fermion line. An analogous relation holds for amplitudes and trivially for the Fock matrix.
