625.10 Macro-Micro Invisible Tetrahedra

625.11 In finite but nonunitarily conceptual Scenario Universe a minimum-system tetrahedron can be physically realized in local time-and-space Universe i.e., as tune-in-able only within human-sense-frequency-range capabilities and only as an inherently two-in-one tetrahedron (one convex, one concave, in congruence) and only by concurrently producing two separate invisible tetrahedra, one externalized macro and one internalized microergo, four tetrahedra.

625.12 The micro-tetra are congruent only in our Universe; in metaphysical Universe they are separate.
