Tiling Space By Platonic Solids I. Olaf Delgado Friedrichs Daniel H. Huson Abstract: There exist precisely 914, 58 and 46 equivariant types of tile-transitive tilings of 3-dimensional euclidean space by topological cubes, octahedra and tetrahedra, that fall in to 11, 3, and 9 topological families, respectively. Representatives are described for all topological families. A general method for obtaining results of this kind is introduced. Discrete and Computational Geometry 21:299-315 (1999).
