The ditetrahedrals consists of three regiments - sidtaxhi, dattady, and gadtaxady. These regiments have 37 polychora each as well as four fissaries (excluding sitphi and gitphi which were mentioned in category 7). These polychora have hyic symmetry with 600 vertices. Their verfs all have tetrahedral symmetry. Sidtaxhi and gadtaxady regiments are conjugates, while the dattady regiment is self conjugate. These polychora are the 4-D analougues of the ditrigonaries in 3-D (sidtid, ditdid, and gidtid)
