622.00 Polarization of Tetrahedron
622.01 The notion that tetrahedra lack polarity is erroneous. There is a polarization of tetrahedra, but it derives only from considering a pair of tetrahedral edge vectors that do not intersect one another. The opposing vector mid-edges have a polar interrelationship.

Fig. 621.10 Falling Sticks: Six Vectors Provide Minimum Stability:
-
Stick standing alone is free to fall in any direction.
-
Two sticks: free to fall in any direction.
-
Two sticks joined: free to fall in two directions and to slide apart at bases.
-
Three sticks: free to fall in any direction.
-
Three sticks joined: only free to slide apart at bases.
-
Four sticks: a propped-up trianglethe prop is free to slide out.
-
Five members: two triangles may collapse as with a hinge action.
-
Six members: complete multidimensional stabilitythe tetrahedron.
622.10 Precessionally Polarized Symmetry: There is a polarization of tetrahedra, but only by taking a pair of opposite edges which are arrayed at 90 degrees (i.e., precessed) to one another in parallelly opposite planes; and only their midpoint edges are axially opposite and do provide a polar axis of spin symmetry of the tetrahedron. There is a fourfold symmetry aspect of the tetrahedron to be viewed as precessionally polarized symmetry.
622.20 Dynamic Equilibrium of Poles of Tetrahedron: There is a dynamic symmetry in the relationship between the mid-action, i.e., mid-edge, points of the opposing pair of polar edges of the tetrahedron. The one dot represents the positive pole of the tetrahedron at mid-action point, i.e., action center. The other dot represents the negative pole of the tetrahedron at midaction point, i.e., at the center of negative energy of the dynamical equilibrium of the tetrahedron.
622.30 Spin Axis of Tetrahedron: The tetrahedron can be spun around its negative event axis or around its positive event axis.
