Domino tilings of squares | MegaFavNumbers
This video is part of the #MegaFavNumbers project. Domino tiling is a tessellation of the region in the Euclidean plane by dominos (2x1 rectangles). In this video we consider square tilings. Sequence, where each element is equal to the number of tilings of an NxN square, is growing reall

Regular tilings of the plane | Elementary Mathematics (K-6) Explained 37 | N J Wildberger
There are three famous regular tilings of the plane, and young people can happily learn about them. They are pleasing, made up of just one tile, which is itself a regular polygon, and have maximal symmetry. Curiously, the underlying tiles are the regular triangle (equilateral triangle), th
