Cubic duotegum

The cubic duotegum, also known as the bidigonal trioprism or digonal trioalterprism, is a noble duotegum that consists of 36 square disphenoids and 16 vertices. It is the first member of the bitrioprisms formed from the convex hull of two rotated trioprisms. It is the first in an infinite family of isogonal digonal dihedral swirlpeta.

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