Abstract
We say that a tile is -morphic if it tiles the plane in exactly many noncongruent ways (up to an isometry). It is an unsolved problem of whether a -morphic tile exist in the plane. In this note we present a construction of a set of convex tiles that is -morphic. The result is interesting since all the constructions of -morphic sets of tiles that arise in the literature make use of bumps and nicks, which necessarily make the tiles non-convex. We construct our set by cleverly dividing the tiles of the set of tiles discovered by Schmitt into convex tiles so that they behave in the same manner.
