24.0 Magic Squares, Higher Order, Composed

24.1 Introduction, Misc. Sub Squares (2)

In Section 9.9.2 Magic Squares of the 9^th order could be constructed based on a set of 9 Magic Squares of the 3^th order,
each containing 9 non-consecutive integers, with corresponding Magic Sum.

Next sections show comparable sets of (Pan) Magic Squares, enabling the construction of 12^th, 15^th, 16^th, 18^th and a few higher order Magic Squares.
