That is, given any two edges, there is an isometry that transforms one edge and its adjacent faces to match the other, but for at least one edge no such isometries are symmetries. ~~~~"

**+942** N Isotoxal polytope Created page with "A polytope is '''isotoxal''' or '''edge-transitive''' if its edges are identical under its symmetry group. In other words, given any two edges, there is a symmetry of the polytope that transforms one into the other. Clearly, an isotoxal polytope must have only one edge length. Isotoxal polytopes as a group are much less studied than isotopic (vertex-transitive) and isogonal (facet-transitive) polytopes. Most isotoxal polygons have degrees of freedom,..."

**+814** N Spirolateral Created page with "'''Spirolaterals''' are a class of polygons, mostly self-intersecting, that generally have a single internal angle and a sequence of edge lengths formed from repetitions of the sequence 1, 2, ..., ''n''. A ''simple spirolateral'' is constructed as follows: draw a 1-unit line segment, turn φ degrees clockwise, draw a 2-unit line segment, turn φ degrees clockwise, ... draw an ''n''-unit line segment, turn φ degrees clockwise, repeat from the beginning...." - 03:5703:57, 19 May 2023

**+853** N Polyomino Created page with "A '''polyomino''' is a non-self-intersecting polygon constructed by joining together one or more unit squares edge to edge. Polyominoes are named by size (number of constituent unit squares) using Greek prefixes: size 2 is the domino, size 3 is the trominoes, size for the tetrominoes, etc. For heptominoes and above, polyominoes may have holes and are therefore may not be simply connected polyominoes; some do not consider these valid. The enumeration of polyo..."

Golygons were investigated by Lee Sallows. The smallest golygon has eight sides, and interestingly can tile the plane. A '''golyhedron''' is a non-self-intersecting polyhedron where all ''n'' faces are polyominoes and have areas 1, 2, ..., ''n''. T..."
