Magic Squares with Centrally Embedded Squares of Odd Order: A Construction Method
Clarence Gipbsin, Lamarr Widmer · viXra · 2021
We present a method which modifies a magic square of odd order n and then adds two outer rows and two outer columns to produce a magic square of order n + 2 . The modification of the original square will preserve the equality of sums of the rows, columns, and main diagonals as well as other significant properties. This modified square will be centrally embedded in the magic square of order n + 2 .
