Hans Walser, [20100824a] Puzzle 4 Except the squares, all polygons can be filled by four kinds of tiles. The tiles have equal area.

However, Akiyama and Thuswaldner computed the neighbor graph for the class of planar self-affine lattice tiles (0.6) associated with canonical number systems and used it to

The Hausdorff dimension is known in particular cases, for example the boundary of tiles associated to canonical number systems (see
