This polychoron is just an edge-faceting of octaco.
It shall be pointed out that in the here being used reduction the x3/2x faces of the top-base 2oct cancel completely out, while their coincident pairs of triangles will get identified instead. (Therefore one might be tempted to name it rather a hollow thah atop oho instead, but then its diametral squares would have to vanish somehow mystically.)
