Swirlchoron

Swirlchora are polychora whose symmetry group is built up in a specific manner from lower-dimensional symmetry groups. Most commonly, swirlchora refer to polychora with symmetry groups built up from a cyclic symmetry group and a polyhedral symmetry group. They're so called because their vertices and faces appear to "swirl" around in various rings, corresponding to great circles of a glome. They are closely related to Hopf fibration and polytwisters.

General swirlchora can be seen as being derived from special kinds of compounds. For instance, the bitetrahedral tetracontoctachoron can be made out of either a compound of eight icositetrachora or four bitetracontoctachora in a specific arrangement. Swirlchora based on cyclic symmetry groups can thus be seen as derived from specific compounds of dihedra.

Being very closely related to quaternions, swirlchora are a phenomenon specific to 4D. Analogues of swirlchora exist in any even number of dimensions, including the eight-dimensional swirlzetta with symmetry groups built up from a polychoric symmetry group and a polyteric symmetry group, which are closely related to octonions.

Swirlchora are always isogonal, and they're often isochoric as well. Examples include the bi-icositetradiminished hexacosichoron and its dual, the tri-icositetradiminished hexacosichoron, which are both isogonal and isochoric, and are therefore noble.
