The truncated square antiprism one in an infinite series of truncated antiprisms, constructed as a truncated square antiprism. It has 18 faces, 2 octagons, 8 hexagons, and 8 squares.

Gyroelongated triamond square bicupola

[edit]

If the hexagons are folded, it can be constructed by regular polygons. Or each folded hexagon can be replaced by two triamonds, adding 8 edges (56), and 4 faces (32). This form is called a gyroelongated triamond square bicupola.[1]

Snub square antiprism

[edit]

Although it can't be made by all regular planar faces, its alternation is the Johnson solid, the snub square antiprism.
