The square bifrustum or square truncated bipyramid is the second in an infinite series of bifrustum polyhedra. It has 4 trapezoid and 2 square faces.

This polyhedron can be constructed by taking a square dipyramid (octahedron) and truncating the polar axis vertices, making is into two end-to-end frustums.
