Decafold tetraswirlchoron

The decafold tetraswirlchoron is an isogonal polychoron with 120 tetragonal disphenoids of two kinds, 120 phyllic disphenoids and 40 vertices. It is the fifth in an infinite family of isogonal tetrahedral swirlchora.

Vertex coordinates
Coordinates for the vertices of a decafold tetraswirlchoron of circumradius 1, centered at the origin, are given by: along with 120° and 240° rotations in the xy axis of: where k is an integer from 0 to 4.
 * ±(0, 0, sin(kπ/5), cos(kπ/5)),
 * ±($\sqrt{6}$sin(kπ/5)/3, $\sqrt{6}$cos(kπ/5)/3, $\sqrt{3}$cos(kπ/5)/3, $\sqrt{3}$sin(kπ/5)/3),

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Edge (40): Decafold tetraswirlchoron
 * Edge (120): Small decafold truncatotetraswirlchoron
 * Edge (120): Great decafold truncatotetraswirlchoron
