The 19-2 gyrochoron, also known as möbius 19, is a convex isotopic polychoron and member of the gyrochoron family with 19 ridge-sextitruncated edge-truncated tetrahedra as cells. It can also be constructed as the 19-9 gyrochoron.
Each cell of this polychoron has bilateral symmetry, with 2 mirror-symmetric heptadecagons, 14 kites, and 2 isosceles triangles for faces, and shares a face with every other cell.
