The numbers {Ig.vix}) were already discussed in connection with the 

 system (78). What distinguishes (86) from (78) is the way in which the 

 variables are connected; the new connection diagram which replaces Fig. 9 

 is shown in Fig. 14. The truncated relations no longer dovetail into each 

 other as they did before. Only the first stage proceeds in a similar way, 

 yielding explicit expressions for (2, 1) and (4, 0). In the next stage we
