In geometry, the square orthobicupola is a Johnson solid constructed by two square cupolas base-to-base.
The square orthobicupola is started by attaching two square cupolae onto their bases.[1] The resulting polyhedron consisted of eight equilateral triangles and ten squares, having eighteen faces in total, as well as thirty-two edges and sixteen vertices. A convex polyhedron in which the faces are all regular polygons is a Johnson solid, and the square orthobicupola is one of them, enumerated as twenty-eighth Johnson solid .[2] This construction is similar to the next one, the square gyrobicupola, which is twisted one of the cupolae around 45°.[1]
