  2. Pentagonal tiling - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_tiling

    Angles are A = 140°, B = 60°, C = 160°, D = 80°, E = 100°. [ 13 ] [ 14 ] In 2016 it could be shown by Bernhard Klaassen that every discrete rotational symmetry type can be represented by a monohedral pentagonal tiling from the same class of pentagons. [ 15 ]

  3. Isohedral figure - Wikipedia

    en.wikipedia.org/wiki/Isohedral_figure

    Similarly, a k-isohedral tiling has k separate symmetry orbits (it may contain m different face shapes, for m = k, or only for some m < k). [ 6 ] ("1-isohedral" is the same as "isohedral".) A monohedral polyhedron or monohedral tiling ( m = 1) has congruent faces, either directly or reflectively, which occur in one or more symmetry positions.

  4. Penrose tiling - Wikipedia

    en.wikipedia.org/wiki/Penrose_tiling

    The original form of Penrose tiling used tiles of four different shapes, but this was later reduced to only two shapes: either two different rhombi, or two different quadrilaterals called kites and darts. The Penrose tilings are obtained by constraining the ways in which these shapes are allowed to fit together in a way that avoids periodic tiling.

  5. Rhombille tiling - Wikipedia

    en.wikipedia.org/wiki/Rhombille_tiling

    In geometry, the rhombille tiling, [1] also known as tumbling blocks, [2] reversible cubes, or the dice lattice, is a tessellation of identical 60° rhombi on the Euclidean plane. Each rhombus has two 60° and two 120° angles; rhombi with this shape are sometimes also called diamonds. Sets of three rhombi meet at their 120° angles, and sets ...

  6. Euclidean tilings by convex regular polygons - Wikipedia

    Therefore, the second problem is that this nomenclature is not unique for each tessellation. In order to solve those problems, GomJau-Hogg’s notation [ 3 ] is a slightly modified version of the research and notation presented in 2012, [ 2 ] about the generation and nomenclature of tessellations and double-layer grids.

  7. Honeycomb (geometry) - Wikipedia

    en.wikipedia.org/wiki/Honeycomb_(geometry)

    Cubic honeycomb. In geometry, a honeycomb is a space filling or close packing of polyhedral or higher-dimensional cells, so that there are no gaps.It is an example of the more general mathematical tiling or tessellation in any number of dimensions.

  8. Cairo pentagonal tiling - Wikipedia

    en.wikipedia.org/wiki/Cairo_pentagonal_tiling

    The Cairo tiling has been described as one of M. C. Escher's "favorite geometric patterns". [7] He used it as the basis for his drawing Shells and Starfish (1941), in the bees-on-flowers segment of his Metamorphosis III (1967–1968), and in several other drawings from 1967–1968.

  9. Unstructured grid - Wikipedia

    en.wikipedia.org/wiki/Unstructured_grid

    Example of unstructured grid for a finite element analysis mesh. An unstructured grid or irregular grid is a tessellation of a part of the Euclidean plane or Euclidean space by simple shapes, such as triangles or tetrahedra, in an irregular pattern. Grids of this type may be used in finite element analysis when the input to be analyzed has an ...
