|Fig. 987.241 Subdivision of Tetrahedral Unity: Octet:
Duo-Tet Cube: Rhombic Dodecahedron:
|A.|| Eighth-Octa composed of six asymmetric tetrahedra.
Each asymmetric tetrahedron is composed of
one A quanta Module and one B Quanta Module. The drawing
is labeled to show the relationship
of the A Modules and the B Modules. Vertex A is at the
center of volume of the octahedron and F
is at the surface of any of the octahedron's eight triangular
|B.|| Proximate assembly of Eighth-Octa and Quarter-Tetra
to be face bonded together as Octet.
|C.|| Octet: (Oc-Tet = octahedron + tetrahedron.) An Eighth-Octa
is face bonded with a Quarter-Tetra to
produce the Octet. (See Sec.
986.430.) The Octet is
composed of 12 A Quanta Modules and 6 B
Quanta Modules. (Compare color plate 22.)
|D, E.|| Duo-Tet Cube: Alternate assemblies of eight Octets
from Duo-Tet Cube. Each Duo-Tet Cube = 3-
|F.|| Rhombic Dodecahedron: Two Duo-Tet Cubes disassociate
their Octet components to be
reassembled into the Rhombic Dodecahedron. Rhombic Dodecahedron
