As abstract polytope sadtap is isomorph to gadtap, thereby replacing decagons by decagrams, resp. dip by stiddip and dedip by stadidip.

Sadtap occurs in 3 different abstract polytopal forms depending on whether the vertices (coincident by 6) will be counted separately (type A), or will be identified (type B). Also edges coincide pairwise, which then might be identified additionally (type C).
