Partially-biexpanded hexateron

The triangular-hexagonal duoprismatic cupoliprism or thiddipcup is a convex scaliform duoprismatic cupoliprism that consists of 2 triangular-hexagonal duoprisms, 6 triangular cupolaic prisms and 6 triangular prismatocupolas.

This polyteron also occurs as two duoprismatic Stott expansions of the hexateron, and can be also called a partially bi-expanded hexateron or pabexhix.

Vertex coordinates
The vertices of a triangular-hexagonal duoprismatic cupoliprism with unit edge length are given by:
 * (0, $\sqrt{51}$/3, 0, ±1, $\sqrt{3}$/6),
 * (±1/2, -$\sqrt{3}$/6, 0, ±1, $\sqrt{3}$/6),
 * (0, $\sqrt{3}$/3, ±$\sqrt{3}$/2, ±1/2, $\sqrt{3}$/6),
 * (±1/2, -$\sqrt{3}$/6, ±$\sqrt{3}$/2, ±1/2, $\sqrt{3}$/6),
 * (±1, 0, $\sqrt{3}$/3, 0, -$\sqrt{3}$/6),
 * (±1/2, ±$\sqrt{3}$/2, $\sqrt{3}$/3, 0, -$\sqrt{3}$/6),
