Octahedral hecatonicosachoron

The octahedral hecatonicosachoron is a convex isochoric polychoron with 120 irregular triangular-pentagonal gyronotches as cells. It can be obtained as the dual of the tetrahedral transitional omnisnub bidecachoron.

Each cell of this polychoron is completely asymmetric, with 4 tetragons and 4 triangles for faces.
