Tetraswirlic hexadecachoron

The 2-tetrahedral swirltegum, also known as the tetswirl 16, is an isochoric polychoron with 16 truncated triangular prisms as cells. Together with its dual, it is the second in an infinite family of tetrahedral swirlchora.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Truncated triangular prism (16): 2-tetrahedral swirlprism
 * Triambus (16): 2-tetrahedral swirlprism
 * Rectangular-symmetric octagon (24): Icositetrachoron
 * Isosceles triangle (48): 6-tetrahedral swirlprism
