This polyteron can be obtained as the convex hull of the 2 jak compound (madek). Here all the edges of the former remain as long ones, while the short ones come in as interconnections of the 2 vertex set members. In the compound the hixes all did form (subdimensional) compounds (stade) in turn. Thus here the hull of those (bidot) is to be used for facets. Note that this fattening to (subdimensional) hulls already fills out everything, i.e. no further facets have to be added here.
