This uniform polyhedron compound is a symmetric arrangement of 6 decagonal prisms, aligned with the axes of fivefold rotational symmetry of a dodecahedron.
Cartesian coordinates
Cartesian coordinates for the vertices of this compound are all the cyclic permutations of
(ñâÂÂ(ÃÂ<sup>âÂÂ1</sup>/âÂÂ5), ñ2ÃÂ, ñâÂÂ(ÃÂ/âÂÂ5))
(ñ(âÂÂ(ÃÂ<sup>âÂÂ1</sup>/âÂÂ5)âÂÂÃÂ<sup>2</sup>), ñ1, ñ(âÂÂ(ÃÂ/âÂÂ5)+ÃÂ))
(ñ(âÂÂ(ÃÂ<sup>âÂÂ1</sup>/âÂÂ5)âÂÂÃÂ), ñÃÂ<sup>2</sup>, ñ(âÂÂ(ÃÂ/âÂÂ5)+1))
(ñ(âÂÂ(ÃÂ<sup>âÂÂ1</sup>/âÂÂ5)+ÃÂ), ñÃÂ<sup>2</sup>, ñ(âÂÂ(ÃÂ/âÂÂ5)âÂÂ1))
(ñ(âÂÂ(ÃÂ<sup>âÂÂ1</sup>/âÂÂ5)+ÃÂ<sup>2</sup>), ñ1, ñ(âÂÂ(ÃÂ/âÂÂ5)âÂÂÃÂ))
where à= (1+âÂÂ5)/2 is the golden ratio (sometimes written ÃÂ).
