A self-tiling tile set, or setiset, of order n is a set of n shapes or pieces, usually planar, each of which can be tiled with smaller replicas of the complete set of n shapes. That is, the n shapes can be assembled in n different ways so as to create larger copies of themselves, where the increase in scale is the same in each case.
In 1961, Wang conjectured that if a finite set of Wang tiles can tile the plane, then there also exists a periodic tiling, which, mathematically, is a tiling that is invariant under translations by vectors in a 2-dimensional lattice. This can be likened to the periodic tiling in a wallpaper pattern, where the overall pattern is a repetition of ...
In geometry, a tiling is a partition of the plane (or any other geometric setting) into closed sets (called tiles), without gaps or overlaps (other than the boundaries of the tiles). [1] A tiling is considered periodic if there exist translations in two independent directions which map the tiling onto itself.

Tantrix is a hexagonal tile-based abstract game invented by Mike McManaway from New Zealand.Each of the 56 different tiles in the set contains three lines, going from one edge of the tile to another.

[1] [2] In March 2023, four researchers, David Smith , Joseph Samuel Myers, Craig S. Kaplan , and Chaim Goodman-Strauss , announced the proof that the tile discovered by David Smith is an aperiodic monotile , i.e., a solution to the einstein problem , a problem that seeks the existence of any single shape aperiodic tile.
