A New Monohedral Hexamorphic Prototile

In this paper we apply the fitting method and a result due to Martin (see [“Polynominoes—A Guide to Puzzles and Problems in Tiling,” The Mathematical Association of American, New York, 1991] to get a hexamorphic prototile different from the only one we have known, presented by Fontaine and Martin in [J. Combin. Theory Ser. A34(1983), 119–121].
