If ``b'' is selected at #20.2 above, the bit pattern will be displayed in 1d or 2d depending on the dimensions of the network. If ``B'' is selected, a 1d network is represented in 2d as a square or rectangular bit pattern, i j. The default i (the number of columns) is set automatically as the highest factor of the network size n. (as for a seed in #15.7.2). The following prompt gives the current ij setting, to revise enter a new i value,
now 15 x 15, reset i-axis : (values shown are examples)
The 1d network is broken up into successive rows starting with the maximum cell index in the top left hand corner. If i is not a factor of n, some cells will be missing from the bottom row.
