In 2-dimensional hyperbolic geometry, the infinite-order pentagonal tiling is a regular tiling. It has Schläfli symbol of {5,âÂÂ}. All vertices are ideal, located at "infinity", seen on the boundary of the Poincaré hyperbolic disk projection.
There is a half symmetry form, , seen with alternating colors:
This tiling is topologically related as a part of sequence of regular polyhedra and tilings with vertex figure (5<sup>n</sup>).
