Summary

[edit]
Description
English: Symmetry Group D2 or 222 on the sphere (2-fold prismatic rotational symmetry).

Yellow triangle is fundamental domain. Numbers are the reflection symmetry order at each node.

This full figure also represents the edges of the polyhedron (V4.4.4) or 3.3.3.3 octahedron expanded onto the surface of a sphere.

This math image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Sphere symmetry group d2.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
