Anisohedral tiling
Tiling forced to use inequivalent tile placements / From Wikipedia, the free encyclopedia
In geometry, a shape is said to be anisohedral if it admits a tiling, but no such tiling is isohedral (tile-transitive); that is, in any tiling by that shape there are two tiles that are not equivalent under any symmetry of the tiling. A tiling by an anisohedral tile is referred to as an anisohedral tiling.[1]
