120/48 = 2 1/2; and there are always both the four
positively skew-rotated
and the four negatively skew-rotated sets of spherical
triangles (two sets of four each),
symmetrically borrowed from among the spherical total
of 20 equiangled, spherical
triangles of each of two spherical icosahedra (each
of radius 1)_which four out of 20
(20/4 = 5) spherical icosahedron's triangles' centers
of area are exactly concentrically
registerable upon every other one of the spherical octahedron's
eight triangles, which areal
centers of the octahedron's eight triangles are also
always concentrically and
symmetrically in register with the eight equiangled,
spherical triangles of the spherical
vector equilibrium when the octahedron and the vector
equilibrium spheres are all of the
same unity-l radius. With this registration of four
out of eight centers of the icosahedron
upon the octahedron-vector equilibrium's eight triangular
surfaces each, we find that one
icosa set of four skews rotationally positive, while
the set of four from another
icosahedron phase registers the negative skew rotation,
which is a +30 degrees or -30
degrees circumferentially-away-from-zero, rotational
askewness for a total of 60 degrees
differential between the extremes of both. The remaining
16 out of the total of 20 triangles
of each of the two different (plus-or-minus-30-degree)
phase icosahedra, subdivide
themselves in four sets of four each, each of which
sets of four arrange themselves in
polarized symmetry upon each of the octahedron's four
other spherical triangles which are
not concentrically occupied by either the positively-
or negatively-skew, concentric sets, of
four each, triangles, neither of which four sets of
four each non-triangularly-concentric
sets repeat the other sets' complementary, asymmetric
but polarized, array in
superimposition upon the octahedron's four nonconcentrically
occupied triangles.
