Claim: Hexagonal tiling (hextille), a regular tiling of the Euclidean plane, in which three hexagons meet at each vertex, is the only regular tiling type in the [6,3] group family of Euclidean uniform tilings.
Evidence: English mathematician John Conway called it a hextille. In geometry, the hexagonal tiling or hexagonal tessellation is a regular tiling of the Euclidean plane, in which three hexagons meet at each vertex. Regular tiling It has Schläfli symbol of {6,3} or t{3,6} (as a truncated triangular tiling). {6,3}
