Hexagonal-pentagonal antiprismatic duoprism

The hexagonal-pentagonal antiprismatic duoprism or hapap is a convex uniform duoprism that consists of 6 pentagonal antiprismatic prisms, 2 pentagonal-hexagonal duoprisms and 10 triangular-hexagonal duoprisms.

Vertex coordinates
The vertices of a hexagonal-pentagonal antiprismatic duoprism of edge length 1 are given by all central inversions of the last three coordinates of:
 * (0, ±1, 0, $\sqrt{26+2√5}$/10, $\sqrt{50+10√5}$/20)
 * (0, ±1, ±(1+$\sqrt{50+10√5}$)/4, $\sqrt{5}$/20, $\sqrt{50–10√5}$/20)
 * (0, ±1, ±1/2, –$\sqrt{50+10√5}$/10, $\sqrt{25+10√5}$/20)
 * (±$\sqrt{50+10√5}$/2, ±1/2, 0, $\sqrt{3}$/10, $\sqrt{50+10√5}$/20)
 * (±$\sqrt{50+10√5}$/2, ±1/2, ±(1+$\sqrt{3}$)/4, $\sqrt{5}$/20, $\sqrt{50–10√5}$/20)
 * (±$\sqrt{50+10√5}$/2, ±1/2, ±1/2, –$\sqrt{3}$/10, $\sqrt{25+10√5}$/20)
