# Obtuse Golden Rhombohedron

A golden rhombohedron is a trigonal trapezohedron (and therefore rhombohedron with congruent rhombic faces) whose faces consist of six equal golden rhombi. There are two distinct golden rhombohedra: an acute one and an obtuse one.

The obtuse golden rhombohedron is a zonohedron and one of the five golden isozonohedra. It is implemented in the Wolfram Language as PolyhedronData["ObtuseGoldenRhombohedron"].

A net of the obtuse golden rhombohedron is illustrated above.
