Bisnub cubic honeycomb

The bisnub cubic honeycomb or bisch is an isogonal honeycomb that consists of pyritohedral icosahedra and tetragonal disphenoids, with 4 of each joining at each vertex. It can be obtained through the process of alternating the bitruncated cubic honeycomb. However, it cannot be made uniform, as it two different edge lengths..

The ratio between the longest and shortest edges is 1:$$\frac{\sqrt6}{2}$$ ≈ 1:1.22474.
