Everything I said was true, except for the stuff about the glide planes. There are no glide planes. There are only simple mirror planes (or lines if you prefer.) Actually, this symmetry is quite common in floor tiling, except that the unit cell usually has reflection symmetry about the diagonals as well. Lew Mammel, Jr. ihnp4!ihuxr!lew
