Biambocubic honeycomb

The biambocubic honeycomb or bamich is an isogonal honeycomb that consists of octahedra and triangular antiprisms. 2 octahedra and 8 triangular antiprisms join at each vertex. It can be obtained as the union of two opposite rectified cubic honeycombs.

The ratio between the longest and shortest edges is 1:$$\sqrt2$$ ≈ 1:1.41421.
