A plot should be described with as few terms
as possible.
Each term should contain as few
variables as possible.
This is accomplished
by using one or more squares any number of
times in combination with one or more squares
not previously used to make groups of 4 or 2
squares.
In the diagram above, there are no
combinations of four potted squares.
The
plotted square in the upper right-hand corer
can be combined with the plotted square
directly beneath it to describe AC; it can
also be combined with the plotted square
immediately to the left to describe AB; and
it can be combined with the plotted square in
the upper left-hand comer to describe BC.
The simplest expression describing this plot
is
a.
ABC+AB+AC.
b.
AB+AC+BC.
c.
ABC+ABC+ABC+ABC.
