A translational tile with no fully periodic tiling in dimension three
Source: github.com/openai/math/tree/main/preprints/A-translational-…
We construct a finite translational tile in ℤ 3 that admits tilings but no fully periodic tiling. Its unit-cube thickening has the same property in ℝ 3 , even when arbitrary real translations are allowed. This gives a negative resolution of the periodic tiling conjecture in dimension three.

Goodman-Strauss of the Museum of Mathematics noted in an email that a paper describing a three-dimensional aperiodic tile has some novel mathematical ideas but is “unnecessarily difficult to read… I figure this is pretty representative across the corpus.” It is, he notes, not remotely close to…
