Domains of Tetrahedron, Octahedron, and Icosahedron:
“The domain of the tetrahedron is the tetrahedron as defined by four spheres in tetrahedronal, omni-embracing, closest-packed tangency network. The domain of an octahedron is an octahedron as defined by six spheres closest packed octahedronally. The domain of an icosahedron is an icosahedron as defined by 12 spheres closest packed without a nucleus. All of the three foregoing non-nuclear-containing domains of the tetrahedron, octahedron, and icosahedron are defined by superficially omnitriangulated closest packing of the four spheres, six spheres, and 12 spheres, respectively, which we have defined elsewhere as omnitriangulated systems or as prime structural systems.”
