Fig. 470.02A Role of Tetrahedra and Octahedra in Vector Equilibrium:
  1. Positive-negative tetrahedron system.
  2. Vector equilibrium formed by four positive-negative tetrahedron systems with common central vertex and coinciding radial edges. Equilibrium of system results from positive-negative action of double radial vectors.
  3. The relationship of space-filling tetrahedra and octahedra to the vector equilibrium defined by eight radially disposed tetrahedra.
