Fig. 470.02A Role of Tetrahedra and Octahedra in Vector
Equilibrium:
- Positive-negative tetrahedron system.
- 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.
- The relationship of space-filling tetrahedra and
octahedra to the vector equilibrium defined by eight
radially disposed tetrahedra.
