Tetraswirlic tetracontachoron

The tetraswirlic tetracontachoron, also known as the tetswirl 40, is an isochoric polychoron with 40 alternate-metatruncated hexagonal prisms as cells. Together with its dual, it is the fifth in an infinite family of tetrahedral swirlchora.

Each cell of this polychoron has a chiral triangular prismatic symmetry, with 2 triangular-symmetric enneagons, 6 mirror-symmetric hexagons, and 6 isosceles triangles for faces.
