- Prismatic compound of prisms with rotational freedom
Each member of this infinite family of
uniform polyhedron compound s is a symmetric arrangement of prisms sharing a common axis of rotational symmetry. It arises from superimposing two copies of the correspondingprismatic compound of prisms (without rotational freedom), and rotating each copy by an equal and opposite angle.This infinite family can be enumerated as follows:
*For each positive integer "n">0 and for each rational number "p"/"q">2, there occurs the compound of 2"n" "p"/"q"-gonal prisms (with rotational freedom), with symmetry group D"np"h.References
