E. Karamuz,R. J. Romanowicz,M. J. Booij polynomial time algorithm which given a graph either finds a skew partition or determines that no such partition exists. It runs in .(. .) time. We present an algorithm for the same problem which runs in .(. . .) time.

Dudeney Transformation of Normal Tiles,. if the plane can be tiled by congruent copies of the polygon which are obtained without turning over the polygon. The numbers of types of convex tiles and convex normal tiles are still uncertain. In this paper, we prove that all convex normal tiles with the same area that we know so far are D-..

Chromatic Numbers of Specified Isohedral Tilings, chromatic number is at most three. By using this fact, we prove that chromatic numbers of specified isohedral tilings with half-turn symmetry are at most three. Then, we notice that self-replicating tiles with fractal boundaries derived from developments of a doubly covered square, which we studied in , are three-colorable in a sense.
