987.130 Primary and Secondary Great-circle Symmetries
987.131 There are seven other secondary symmetries based on the pairing into spin poles of vertexes produced by the complex secondary crossings of one another of the seven original great circle symmetries.

Fig. 987.132F 		987.132 The primary and secondary icosa symmetries altogether comprise 121 = 112 great circles. (See Fig. 987.132E.)
987.133 The crossing of the primary 12 great circles of the VE at G (see Fig. 453.01, as revised in third printing) results in 12 new axes to generate 12 new great circles. (See color plate 12.)
987.134 The crossing of the primary 12 great circles of the VE and the four great circles of the VE at C (Fig. 453.01) results in 24 new axes to generate 24 new great circles. (See color plate 13.)
987.135 The crossing of the primary 12 great circles of the VE and the six great circles of the VE at E (Fig. 453.01) results in 12 new axes to generate 12 new great circles. (See color plate 14.)
987.136 The remaining crossing of the primary 12 great circles of the VE at F (Fig. 453.01 results in 24 more axes to generate 24 new great circles. (See color plate 15.)

987.200 Cleavagings Generate Polyhedral Resultants

Fig. 987.210 		987.210 Symmetry #1 and Cleavage #1
987.211 In Symmetry #l and Cleavage #1 three great circles-the lines in Figs. 987.210 A through F__are successively and cleavingly spun by using the midpoints of each of the tetrahedron's six edges as the six poles of three intersymmetrical axes of spinning to fractionate the primitive tetrahedron, first into the 12 equi-vector-edged octa, eight Eighth-octa (each of l/2-tetravolume), and four regular tetra (each of l-tetravolume).
987.212 A simple example of Symmetry #1 appears at Fig. 835.11. Cleavage #1 is illustrated at Fig. 987.210E.
987.213 Figs. 987.210A-E demonstrate Cleavage #1 in the following sequences: (1) The red great circling cleaves the tetrahedron into two asymmetric but identically formed and identically volumed "chef's hat" halves of the initial primitive tetrahedron (Fig. 987.210). (2) The blue great circling cleavage of each of the two "chef's hat" halves divides them into four identically formed and identically volumed "iceberg" asymmetrical quarterings of the initial primitive tetrahedron (Fig. 987.210B). (3) The yellow great circling cleavage of the four "icebergs" into two conformal types of equivolumed one- Eighthings of the initial primitive tetrahedron__four of these one-Eighthings being regular tetra of half the vector-edge-length of the original tetra and four of these one-Eighthings being asymmetrical tetrahedra quarter octa with five of their six edges having a length of the unit vector = 1 and the sixth edge having a length of sqrt(2) = 1.414214. (Fig. 987.210C.)
987.220 Symmetry #2 and Cleavage #4:

Fig. 987.221 		987.221 In Symmetry #2 and Cleavage #4 the four-great-circle cleavage of the octahedron is accomplished through spinning the four axes between the octahedron's eight midface polar points, which were produced by Cleavage #2. This symmetrical four-great- circle spinning introduces the nucleated 12 unit-radius spheres closest packed around one unit-radius sphere with the 24 equi-vector outer-edge-chorded and the 24 equi-vector- lengthed, congruently paired radii__a system called the vector equilibrium. The VE has 12 external vertexes around one center-of-volume vertex, and altogether they locate the centers of volume of the 12 unit-radius spheres closest packed around one central or one nuclear event's locus-identifying, omnidirectionally tangent, unit-radius nuclear sphere.
987.222 The vectorial and gravitational proclivities of nuclear convergence of all synergetics' system interrelationships intercoordinatingly and intertransformingly permit and realistically account all radiant entropic growth of systems as well as all gravitational coherence, symmetrical contraction, and shrinkage of systems. Entropic radiation and dissipation growth and syntropic gravitational-integrity convergency uniquely differentiate synergetics' natural coordinates from the XYZ-centimeter-gram-second abstract coordinates of conventional formalized science with its omniinterperpendicular and omniinterparallel nucleus-void frame of coordinate event referencing.
987.223 Symmetry #2 is illustrated at Fig. 841.15A.
