%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.)
%e A056472 E.g. 12=2.6=2.2.3=3.4
