Dodecagonal-octahedral duoprism

The dodecagonal-octahedral duoprism or twoct is a convex uniform duoprism that consists of 12 octahedral prisms and 8 triangular-dodecagonal duoprisms.

Vertex coordinates
The vertices of a dodecagonal-octahedral duoprism of edge length 1 are given by all permutations and sign changes of the last three coordinates of:
 * (±(1+$\sqrt{10+4√3}$)/2, ±(1+$\sqrt{3}$)/2, 0, 0, $\sqrt{3}$/2)
 * (±1/2, ±(2+$\sqrt{2}$)/2, 0, 0, $\sqrt{3}$/2)
 * (±(2+$\sqrt{2}$)/2, ±1/2, 0, 0, $\sqrt{3}$/2)
