# 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.
