These squares have complementary numbers that:
These can be transformed from/to concentric magic squares by repeating transform 2. Swap all pairs of rows on the top side of the square in increasing sequence, e.g., for orders 9 and 10, swap rows (1 2), (1 3), (1 4), (2 3), (2 4), (3 4).
SymlateralSquares makes these squares.
The center 3x3 square can be any center of an odd concentric magic square of the same order including any aspect of the Lo Shu square.
Each order n bones is conceptually made from the n-2 bones by:
The center 4x4 square can be any center of an even concentric magic square of the same order including any aspect of the 880 order 4 squares.
These are conceptually made as for odd order bones, but reserving two middle rows and columns here, (see octant boundaries).
Note 1: ½ has been omitted from all the bones numbers displayed here. Therefore, to convert these displayed bones numbers to the actual square numbers:
Note 2: Here the outside cells of the middle rows and middle columns are not middle symmetric.
