Looks like a compound of 2 tetrahedra (tet) with vertices identified, edges and faces both coincide by pairs.

(Here sefa( β3/2x3o ) degenerates to a point,
thus 3 points each from x3/2x3o will be identified.)

(Here the tetragons sefa( x3/2β3o ) degenerate to a line,
thus their remaining edges, sefa( β3o ), will be identified,
alike pairwise their vertices.)
