Combinations and Permutations

            To Keep It Simple Stupid (KISS), consider thinking about the subjects this way:

1) Having a drawing with various pieces that you can combine to make one bigger piece.

2) Having the same drawing where you can arrange the pieces in various orders. That is making  permutations.

3) Planning your own home defense, for example,  may gain advantages by considering your possible combinations or permutations of your own efforts. Like which comes first.....a diagram for all to see and hopefully understand, or initial  physical work, or some variation of both.
