Gyrobifastigial 5-2 quadruple step prism

The gyrobifastigial 5-2 quadruple step prism is a convex isogonal polychoron formed as a convex hull of four 5-2 step prisms in a way that leaves eight corealmic vertices corresponding to a gyrobifastigium. It consists of 5 gyrobifastigiums, 10 wedges and 10 phyllic disphenoids.

It can be constructed as a diminishing of a uniform small rhombated pentachoron.

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