Prismatic compound of prisms

Short description: Polyhedral compound

Compound of n p/q-gonal prisms
(n=2, p=5, q=2)
Type	Uniform compound
Index	UC21
Polyhedra	n p/q-gonal prisms
Faces	2n {p/q}, np squares
Edges	3np
Vertices	2np
Symmetry group	np-fold prismatic (Dnph)
Subgroup restricting to one constituent	p-fold prismatic (Dph)

Each member of this infinite family of uniform polyhedron compounds is a symmetric arrangement of prisms sharing a common axis of rotational symmetry.

This infinite family can be enumerated as follows:

• For each positive integer n≥1 and for each rational number p/q>2 (expressed with p and q coprime), there occurs the compound of n p/q-gonal prisms, with symmetry group D_nph.
