%N A056472 Triangle read by rows in which row n lists all factorizations of n.
%C A056472 n comes first, then minimal factorization (12=2.6). Resultant factor 
               is further resolved as much as possible, (2.6=2.2.3). The natural 
               number or initial factors are then incremented, (3.4, 13.)
