16-3 gyrochoron

The 16-3 gyrochoron, also known as gyrus 16, is a convex isochoric polychoron and member of the gyrochoron family with 16 identical cells. It can also be constructed as the 16-5 gyrochoron. Together with its dual, it is the third in an infinite family of square dihedral swirlchora.

Each cell of this polychoron has mirror symmetry, with 2 decagons, 2 hexagons, 4 tetragons, and 4 triangles for faces.
