context_page_description: A enneadecahedron is a polyhedron with 19 faces. No enneadecahedron is regular; hence, the name is ambiguous.
  There are numerous topologically distinct forms of an enneadecahedron, for example the octadecagonal pyramid, or the heptadecagonal prism; the latter is the only convex enneadecahedron with all regular polygonal faces.
