1985: Stein discovers the 14th type of pentagonal tiling of the plane.
2015: Mann, McLoud, & Von Derauthe discover the 15th pentagonal tiling.
2017: Rao proves there are no additional ways to tile the plane with convex pentagons.
To the MNS presentation* In how many ways can we tile the plane by polygons, vertex-to-vertex and edge-to-edge, without gaps and overlaps?
* Kepler: There are 11 ways to tile the plane with regular polygons – three by using one polygon, and eight by using several polygons
To the MNS presentation* Regular polygons
* Symmetry
* Tiling
* Plane
* Angle, Vertex, Edge
* Convex polygon
* Reflection
* Translation
