Partially-biexpanded demihexeract

The partially-biexpanded demipenteract or pabex hax, also known as the truncated tetrahedral duoalterprism, is a convex scaliform polypeton that consists of 12 partially-expanded demipenteracts, 16 triangular-tetrahedral duoprisms, 24 truncated tetrahedral cupoliprismatic prisms and 32 partially-biexpanded hexatera formed by tetrahedrally alternating the small rhombicuboctahedral duoprism.

It can also be obtained as two Stott expansions of the demihexeract.

Vertex coordinates
The vertices of a partially-biexpanded demihexeract of edge length 1, are given by all permutations and even changes of sign of the first and last three coordinates of:
 * ±($\sqrt{11}$/4, $\sqrt{2}$/4, 3$\sqrt{2}$/4, $\sqrt{2}$/4, $\sqrt{2}$/4, 3$\sqrt{2}$/4).
