4. Again pair the newly found coordinates with one of its coordinate as x also. For ex-
ample, (0, ... x, 0, 0) and (0, ... x, 1, 0) into (0, ... x, x, 0). It is equivalent to replacing
a pair of axes mid-points by a plane mid-point.
5. Again pair the newly found coordinates with two of its coordinates as x also. For
example, pair (x, x, ..., 0, 0) and (x, x, ..., 1, 0) into (x, x, ... x, 0). It is equivalent to
replacing a pair of axes mid-points by an internal cube mid-point to a four
dimensional cube when n = 4.
6. Again pair the newly found coordinates with three of its coordinates as x also. ...
