Duoprismatic swirlprism

In four dimensions, a duoprismatic swirlprism or m-n-gonal p-swirlprism is an isogonal polychoron formed from an (m*p-n*p)-gonal duoprism by reducing the (m*p)-gonal and (n*p)-gonal prisms into swirling m-gonal and n-gonal antprisms, which are generally uniform except for one trivial case. They are also the swirlchora based on a dihedron. The hexadecachoron is the simplest duoprismatic swirlprism, being the digonal diswirlprism, while the digonal-triangular triswirlprism is the simplest nontrivial duoprismatic swirlprism.

If m and n are equal to 2, then the resulting polychoron is equivalent to the 2p-gonal duotegum and if p is equal to 2, then the resulting polychoron is equivalent to the m-n duoantiprism.
