The square antiwedge, or squaw, also sometimes called the square gyrobicupolic ring, is a CRF segmentochoron (designated K-4.64 on Richard Klitzing's list). It consists of 1 square antiprism, 2 square cupolas, and 8 square pyramids.
The square antiwedge can be thought of as a piece of the larger segmentochoron cuboctahedron atop small rhombicuboctahedron, with one base square being a face of the cuboctahedron, and the opposite square cupola being part of the small rhombicuboctahedron.

Representations[edit | edit source]
A square antiwedge has the following Coxeter diagrams:
- os2xo8os&#x (full symmetry)
- xxo4oxx&#x (BC2 symmetry only, seen with square atop gyro square cupola)
