Axes of Rotation of Vector Equilibrium:
 Rotation of vector equilibrium on axes through centers
of opposite trianglar faces defines four
equatorial greatcircle planes.
 Rotation of the vector equilibrium on axes through
centers of opposite square faces defines three
equatorial greatcircle planes.
 Rotation of vector equilibrium on axes through opposite
vertexes defines six equatorial greatcircle
planes.
 Rotation of the vector equilibrium on axes through
centers of opposite edges defines twelve
equatorial greatcircle planes.
