As an axial gyrated blend it has a pseudo bottom face. That one is the withdrawn 2{6} of the corresponding composition. By that withdrawel the top base, when considered as a single compound (type A), becomes a membran, as the central part becomes accessible from the outside at both sides, when being considered as 2 coplanar triangles instead (type B) it becomes a Grünbaumian membran: that central region of those 2 coplanar triangles is accessable from both sides. (Mod-2 fillings so would even erase that central bit completely, the hole then would run through.)
