6. Again pair the newly found coordinates with three of its coordinates being
x. For example, pair (x, x, x, 0) and (x, x, x, 1) into (x, x, x, x). It is equiva-
lent to replacing a pair of axes mid-points by the four dimensional cube
mid-point.
Exemplary steps in computer based minimization (finding prime implicants) of
Equation (3.13) based on four-dimensional cube are as follows
