In geometry, the infinite-order triangular tiling is a regular tiling of the hyperbolic plane with a Schläfli symbol of {3,∞}. All vertices are ideal, located at "infinity" and seen on the boundary of the Poincaré hyperbolic disk projection.

Symmetry[edit]

A lower symmetry form has alternating colors, and represented by cyclic symbol {(3,∞,3)}, CDel node 1.pngCDel split1.pngCDel branch.pngCDel labelinfin.png. The tiling also represents the fundamental domains of the *∞∞∞ symmetry, which can be seen with 3 colors of lines representing 3 mirrors of the construction.
