Border Square
A Magic Square that remains magic when its border is removed. A nested magic square remains magic after the border issuccessively removed one ring at a time. An example of a nested magic square is the order 7 square illustrated above (i.e.,the order 7, 5, and 3 squares obtained from it are all magic).
