Note that on dritit, the edges that connect stars to squares look like two different classes, but in rappisdi, they become one class. Same with the edges where pentagons meet squares. Also the squares themselves look like two classes in the verf, but become one class in rappisdi.

This polychoron has ionic icoic symmetry.
