Pyritorhombidodecaswirlic heptacontadichoron

The pyritorhombidodecaswirlic heptacontadichoron is an isochoric polychoron with 72 identical cells. It is the first in an infinite family of isochoric pyritohedral rhombic dodecahedral swirlchora.

Each cell of this polychoron has chiral digonal prismatic symmetry, with 4 mirror-symmetric heptagons, 2 rhombi, 4 kites, and 4 isosceles triangles for faces.
