24-7 step prism

The 24-7 step prism, also known as the digonal double triswirlprism, is a convex isogonal polychoron, member of the step prism family. It has 24 rhombic disphenoids and 96 phyllic disphenoids of two kinds as cells. It is the second in an infinite family of isogonal digonal prismatic swirlchora.
