As Bunge points out, however, the shortest set of lines connecting all five points does not in fact contain any of the elements shown in the previous diagrams. This shortest set solution is given in Figure 3.8E. Note, as we would expect from the discussion earlier in this section, that this solution consists of seven line segments meeting at three junctions so located that all segments meet at 120° angles. Finally, Figure 3.8F shows the general topological case for a network of lines connecting five points as presented by Beckmann (Bunge, 1962, p. 189). Examination of this final diagram shows that the two preceding cases the completely linked network (D) and the shortest link network (E)- are but special cases of Beckmann's general network.
