Permanents and determinants of (0,1) matrices

[Meeussen Wouter (bkarnd)]

Aha, a pro at work! nice!


can you also do something similar with
the row-and-column sorted (0,1) matrices?

What happens to the graph when you swap two rows
or two columns?
the explanations in
http://mathworld.wolfram.com/BipartiteGraph.html
do not *instantaneously* pierce my ignorence.
