Tetraswirlic hexadecachoron

The tetraswirlic hexadecachoron, also known as the tetswirl 16 or the digonal double chiroantitegum, is an isochoric polychoron with 16 truncated triangular prisms as cells. It is the second in an infinite family of isochoric tetrahedral swirlchora.

Each cell of this polychoron has a chiral triangular prismatic symmetry with 2 triambi (triangular-symmetric hexagons), 3 rectangle-symmetric octagons, and 6 isosceles triangles for faces.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Truncated triangular prism (16): Tetrafold tetraswirlchoron
 * Triambus (16): Tetrafold tetraswirlchoron
 * Rectangular-symmetric octagon (24): Tetrafold ambotetraswirlchoron
 * Isosceles triangle (48): Dodecafold tetraswirlchoron
