If one looks at the projections 84, the gaps 38 and the pockets 44, which are seen in the edge formation 30 of the first type in the drawing right-bottom, also on the opposite Having added parallel edge presents, one has to imagine how a normal element 6 designed with stiffening tubes 86 looks like.
