Icosahedron

An icosahedron is a 20-faced polyhedron.

Examples include the decagonal dipyramid, elongated triangular gyrobicupola (Johnson solid ), elongated triangular orthobicupola (), gyroelongated triangular cupola (), Jessen's orthogonal polyhedron, metabiaugmented dodecahedron (), nonagonal antiprism, parabiaugmented dodecahedron (), 18-gonal prism, 19-gonal pyramid, regular icosahedron, and rhombic icosahedron.

Icosahedron

A polyhedron with 20 faces, usually referring to the triangular icosahedron, one of the five platonic solids. (pl. icosahedra, more rarely icosahedrons)

Examples of icosahedra are the decagonal bipyramid, the decagonal trapezohedron, the octadecagonal prism, the enneadecagonal pyramid, the enneagonal antiprism, and the platonic icosahedron

It's the only shape with equal power to the octahedron, and was used by Meme Man to defeat Orang.

you cannot defeat me, orang, for i have the icosahedron of capacity.
