'''Demiregular Tessellations''' are comprised of repetitions of two or more regular polygons, where the number and type of each kind of polygon surrounding each vertex is different for some of the vertices in the plane. Although it can be argued that the number of such tessellations is infinite, they can be reduced to 14 specific types.

Other tessellations of the plane exist. See for example the tilings of [[M.C. Escher]].  

 

Other tessellations of the plane exist. See for example the tilings of [[M.C. Escher]], such as the one which is illustrated here. Such tilings are not tessellations, in that they are not comprised of polygons. However, these tilings are based on one of the above named types of tessellation.

 

The tiling illustrated is based on a regular tessellation of squares.
