#	Rhombic Dodecahedron 3-Torus
#
#	The quotient of E³ by translations in the directions
#	of the faces of a rhombic dodecahedron. Such a construction
#	won't work with an arbitrary polyhedron, but works great
#	with a rhombic dodecahedron because rhombic dodecahedra tile E³.
#
#	The first three elements in the bottom row
#	of each matrix define the translation vectors.
