Einstein Tiles

A sequence of aperiodic hat tiles, with their associated metatile and supertile outlines.

The mathematical structure is described in the paper “An aperiodic monotile” (Smith, Myers, Kaplan, and Goodman-Strauss, 2023).

An Einstein Tile is a 13-sided polykite shape that when tiled never repeats itself.
