dodecahedron

"There are other sizes of dodecahedron in existence which could be more portable to carry if the army was on the move," Dr Foyle countered.

The object is one of only 33 dodecahedrons ever found in Britain, and the first to have been discovered in the Midlands.

You start out with a simple solid — most frequently a dodecahedron, or a solid with twelve pentagonal faces — and then form the star’s points by extruding each edge.

Granted, the shape is dramatically different than the one that existed when minor-league ball was shuttered last summer — like a square becoming a dodecahedron.

These are the five convex polyhedra—tetrahedron, cube, octahedron, dodecahedron, and icosahedron—that are made of congruent regular polygons.
