636.00 Complementary to Vector Equilibrium

636.01 In the vector equilibrium, we have all the sets of tetrahedra bivalently or edge-joined, i.e., liquidly, as well as centrally univalent. Synergetics calls the basally developed larger tetrahedron the non-mirror-imaged complementary of the vector equilibrium[^23]. In vectorial-energy content and dynamic-symmetry content lies the complementarity.
