16-6 step prism

The 16-6 step prism is a convex isogonal polychoron and a member of the step prism family. It has 8 rhombic disphenoids and 48 phyllic disphenoids of three kinds as cells, with 14 (2 rhombic and 12 phyllic disphenoids) joining at each vertex. It is also the hexagonal funk tegum.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{\sqrt{10088+4656\sqrt2+194\sqrt{170+71\sqrt2}}}{97}$$ ≈ 1:1.45294.

Vertex coordinates
Coordinates for the vertices of a 16-6 step prism inscribed in a hexadecagonal duoprism with base lengths a and b are given by: where k is an integer from 0 to 15. If the edge length differences are to be minimized, the ratio of a:b must be equivalent to 1:$$\frac{\sqrt{8-4\sqrt2+2\sqrt{4-2\sqrt2}}}{2}$$ ≈ 1:1.06159.
