Polyhedron
A polyhedron is a three-dimensional  geometric shape whose sides are comprised of flat polygonal surfaces (faces). The faces meet in edges which are straight-line segments, and the edges meet in points called vertices. Polyhedrons are named after the number of faces.

In 2376, Icheb created a 26-sided polyhedron out of clay, composed of hexagons, octagons, and squares: a truncated cuboctahedron. Seven of Nine was impressed by Icheb's work. ()

The Kelvan Empire had technology capable of nearly instantaneously converting humanoids into much smaller polyhedra, specifically cuboctahedra. ()
