Concentric Magic Squares

A concentric magic square contains more than one magic square. It embodies smaller magic squares concentrically. This technique only works with odd order magic squares; i.e., squares that contain an uneven number of squares along a side, such as 3, or 7, 25, etc. This book presents several examples, including a 25x25 concentric magic square, whcih contains 625 contiguous, non-dupliocate numbers in all.
