The **square antipodium** or **squapo** is a variant of the square antiprism where the bases are different sized squares. The version with all equal edges is the uniform square antiprism, but other versions exist with isosceles triangles as the sides. In the latter case its Coxeter diagram could be given as xo4oy&#z.
