The medial rotational 8-3 bigyrochoron, also known as the cracked 16, is a convex isochoric polychoron with 16 identical cells.
Each cell of this polychoron is completely asymmetric, with 2 irregular enneagons, 1 mirror-symmetric hexagon, 2 irregular hexagons, 1 kite, 2 irregular tetragons, and 4 scalene triangles for faces.
