Uniform tilings in hyperbolic planeIn hyperbolic geometry, a uniform hyperbolic tiling (or regular, quasiregular or semiregular hyperbolic tiling) is an edge-to-edge filling of the hyperbolic plane which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other). It follows that all vertices are congruent, and the tiling has a high degree of rotational and translational symmetry.
Uniform tilingIn geometry, a uniform tiling is a tessellation of the plane by regular polygon faces with the restriction of being vertex-transitive. Uniform tilings can exist in both the Euclidean plane and hyperbolic plane. Uniform tilings are related to the finite uniform polyhedra which can be considered uniform tilings of the sphere. Most uniform tilings can be made from a Wythoff construction starting with a symmetry group and a singular generator point inside of the fundamental domain.
Rhombitriheptagonal tilingIn geometry, the rhombitriheptagonal tiling is a semiregular tiling of the hyperbolic plane. At each vertex of the tiling there is one triangle and one heptagon, alternating between two squares. The tiling has Schläfli symbol rr{7, 3}. It can be seen as constructed as a rectified triheptagonal tiling, r{7,3}, as well as an expanded heptagonal tiling or expanded order-7 triangular tiling. The dual tiling is called a deltoidal triheptagonal tiling, and consists of congruent kites.
Pavage trihexagonalLe pavage trihexagonal est, en géométrie, un pavage semi-régulier du plan euclidien, constitué de triangles équilatéraux et d'hexagones. Au Japon, ce pavage est utilisé en vannerie sous le nom de Kagomé. En physique, ce pavage est appelé réseau de Kagomé d'après le terme japonais. On l'observe dans la structure cristalline de certains matériaux, notamment l'herbertsmithite. Il est très étudié en magnétisme car sa frustration géométrique génère des phases magnétiques exotiques, comme le liquide de spin. Tri
Polyèdre quasi régulierUn polyèdre dont les faces sont des polygones réguliers, qui est transitif sur ses sommets, et qui est transitif sur ses arêtes, est dit quasi régulier. Un polyèdre quasi régulier peut avoir des faces de deux sortes seulement, et celles-ci doivent alterner autour de chaque sommet. Pour certains polyèdres quasi réguliers : on utilise un symbole de Schläfli vertical pour représenter le polyèdre quasi régulier combinant les faces du polyèdre régulier {p,q} et celles du dual régulier {q,p} : leur noyau commun.
List of Euclidean uniform tilingsThis table shows the 11 convex uniform tilings (regular and semiregular) of the Euclidean plane, and their dual tilings. There are three regular and eight semiregular tilings in the plane. The semiregular tilings form new tilings from their duals, each made from one type of irregular face. John Conway called these uniform duals Catalan tilings, in parallel to the Catalan solid polyhedra. Uniform tilings are listed by their vertex configuration, the sequence of faces that exist on each vertex. For example 4.
