"Therefore there is in the Changes the Great Primal Beginning. This generates the two primary forces. The two primary forces generate the four images. The four images generate the eight trigrams. The eight trigrams determine good fortune and misfortune. Good fortune and misfortune create the great field of action." (Commentary on I Ching, tr. Wilhelm and Baynes 1967:318-9)

  1. The star tetrahedron, also known as the stellated octahedron, or "stella octangula," shares the same vertex arrangement as the cube.

    When the faces of a regular octahedron are exchanged for vertices (and conversely), the cube results. This is called a 'reciprocal' or 'dual' relationship. The diagram above depicts a geometrical connection between these three.
