  1. Catalog of Isohedral Tilings by Symmetric Polygonal Tiles - Doris Schattschneider
    A collection of Sketchpad and JavaSketchpad files supplementing the article "One Corona is Enough for the Euclidean Plane" by mathematicians Doris Schattschneider and Nikolai Dolbilin. Tilings of the Euclidean plane by a single polygon are considered, and it is shown that such a tiling is isohedral if and only if each polygon is "surrounded in the same way," or, more technically, the centered coronas of tiles are pairwise congruent. more>>
