Abstract
Polyominoes, shapes made up of squares connected edge-to-edge, provide a rich source of prototiles for edge-to- edge fractal tilings. We give examples of fractal tilings with 2-fold and 4-fold rotational symmetry based on prototiles derived by dissecting polyominoes with 2-fold and 4-fold rotational symmetry, respectively. A systematic analysis is made of candidate prototiles based on lower-order polyominoes. In some of these fractal tilings, polyomino-shaped holes occur repeatedly with each new generation. We also give an example of a fractal knot created by marking such tiles with Celtic-knot-like graphics.

[10] The only pentomino with 4-fold rotational symmetry yields prototiles with 3 short edges. Adding 4 squares to this pentomino yields prototiles with either 3 or 5 short pseudo-edges. It can easily be seen that adding four squares to any 4-fold polyomino will either add 2 short pseudo-edges, leave the number of short pseudo-edges unchanged, or subtract 2 short pseudo-edges. The number of short pseudo-edges for prototiles is therefore always odd.
