The 16-4 gyrochoron, also known as the square tetracoil, is a convex isochoric polychoron and member of the gyrochoron family with 16 ridge-truncated tetragonal antiwedges as cells.
Each cell of this polychoron has bilateral symmetry, with 2 mirror-symmetric hexagons, 2 kites, and 4 isosceles triangles for faces.
