If ``r'' is selected in 9.3, a wiring scheme will be assigned at random according to the previously selected neighbourhood (and mix) settings. The next prompt allows a 1d ``wiring graphic'' or a ``wiring matrix'' to be displayed, and the wiring to be reviewed and altered in various ways (see #12).
To restrict random wiring in various ways(see #11.5), select ``s'' for ``special'' wiring'' in #9.3 before selecting random wiring.
