The small sphenoidal heptachiliadiacosichoron is a convex isochoric polychoron with 7200 sphenoids as cells. It can be obtained as the dual of the great rhombated hexacosichoron.
It can also be constructed as the convex hull of a hecatonicosachoron, a hexacosichoron, and a rectified hexacosichoron. If the hecatonicosachoron has edge length 1, the hexacosichoron has edge length and the rectified hexacosichoron has edge length .
