986.312 These 120 right spherical surface triangles are described by three different central angles of
986.313 These diamonds, like all diamonds, are rhombic forms. The 30-symmetrical-diamond system is called the rhombic triacontahedron, its 30 mid-diamond faces (right-angle cross points) are approximately tangent to the unit-vector-radius sphere when the volume of the rhombic triacontahedron is exactly tetravolume-5. (See Fig. 986.314.)
986.314 I therefore asked Robert Grip and Chris Kitrick to prepare a graphic comparison of the various radii and their respective polyhedral profiles of all the symmetric polyhedra of tetravolume 5 (or close to 5) existing within the primitive cosmic hierarchy (Sec. 982.62)i.e. other than those of tetravolumes 1, 2, 3, 4, and 6which carefully drafted drawing of the tetravolume-5 polyhedra (and those polyhedra “approximately” tetravolume 5) my colleagues did prepare (see Fig. 986.314). These exactly tetravolume-5 polyhedra are, for example
-
the icosahedron with outer edges of unit vector length;
-
the icosahedron of outer vertex radius of unit vector length;
-
the regular dodecahedron of unit vector edge; and
-
the regular dodecahedron of unit vector radius
all of which show that they have only a slightly greater radius length than that of the prime vector.

986.315 The chart of the polyhedral profiles (Fig. 986.314) shows the triacontahedron of tetravolume 5 having its mid-diamond-face point
986.316 By careful study of the Grip-Kitrick drawings of tetravolume-5 polyhedra it is discovered that the graphically displayed zones of radial proximity to one another of all the tetravolume-5 symmetric polyhedra (Fig. 986.314) describe such meager radial differences at their respective systems outermost points as to suggest that their circumferential zone enclosed between the most extremely varied and the most inwardly radiused of all their axially spun vertexes of the exact tetravolume-5 polyhedra may altogether be assumed to constitute the zone of limit cases of radiantly swept-out and pulsating tetravolume-5 kinetic systems.
986.317 Recognizing that polyhedra are closed systems and that there are only seven cases of symmetrical subdivisioning of systems by the most economical great-circle spinnings (and most economically by the chords of the great-circle arcs), we discover and prove structurally that the maximum-limit abundance of a unit-symmetrical-polyhedral-system’s identical facetings is the rhombic triacontahedron, each of whose 30 symmetrical diamond planar faces may be symmetrically subdivided into four identical right triangles

The central and surface angles of the two pentahedra differ as shown.
