Isotoxal figure
Polytope or tiling with one type of edge / From Wikipedia, the free encyclopedia
This article is about geometry. For edge transitivity in graph theory, see Edge-transitive graph.
In geometry, a polytope (for example, a polygon or a polyhedron) or a tiling is isotoxal (from Greek τόξον 'arc') or edge-transitive if its symmetries act transitively on its edges. Informally, this means that there is only one type of edge to the object: given two edges, there is a translation, rotation, and/or reflection that will move one edge to the other while leaving the region occupied by the object unchanged.
