Swirlchoron

A swirlchoron is a polychoron that expresses the Hopf fibration of a given polyhedron. In other words, the vertices or cells of a polychoron map to a ring of swirling great circles within a glome that represents a face of a polytwister, and are therefore their polychoric approximations. For every regular spherical polyhedron (including degenerate dihedra/hosohedra), a swirlchoron can be constructed. Their vertices can be compounded to form new swirlchora, an example being the 1-bitetrahedral swirlprism, being the compound of two hexadecachora in tetrahedral swirlprism symmetry, or the tri-icositetradiminished hexacosichoron, being the tetragonal-antiwedge compound of two icositetrachora in cubic swirlprism symmetry.

There are two types of swirlchora. Swirlprisms are isogonal and can be thought as duals to the swirltegums, which are isochoric. Some swirlchora, such as the bi-icositetradiminished hexacosichoron and its dual, the tri-icositetradiminished hexacosichoron, are both isogonal and isochoric, and are therefore noble.

Coordinates for the vertices of a 4n-fold octaswirlchoron of circumradius 1, centered at the origin, are given by all permutations and sign changes of: defining an icositetrachoron, along with reflections through the x=y and z=w hyperplanes ({x,y,z,w} = {z,w,x,y} = {y,x,w,z} = {w,z,y,x}) and with all sign changes of (k represents any number from 1 up to floor(n/2)): along with reflections through the x=y and z=w hyperplanes and with all even sign changes of (if n is odd, then k represents any odd number from 1 up to n; if n is even, then k represents any number from 0 up to n/2): along with reflections through the x=y and z=w hyperplanes and with all odd sign changes of:
