The hull of this degenerate shape is haxt. In fact, the latter provides 2 different decompositions, either into 12 hinscs plus 32 ocas (kind in the sense of a 7D orange) or equatorially into 2 haxpies. The blend of these 2 decompositions, blending out right those haxt cells each, then would result in haxesc again.

In fact, it is only this degeneracy, which lets become here the hull of a scalene to be a mere bipyramid.
