Editing Frénicle standard form (section)

==Properties==
This standard form was devised since a magic square remains "essentially similar" if it is rotated or [[transpose]]d, or flipped so that the order of rows is reversed. There exist 8 different magic squares sharing one standard form. 
For example, the following magic squares are all essentially similar, with only the final square being in the Frénicle standard form:

  8 1 6   8 3 4     4 9 2   4 3 8     6 7 2   6 1 8     2 9 4   '''2 7 6'''
  3 5 7   1 5 9     3 5 7   9 5 1     1 5 9   7 5 3     7 5 3   '''9 5 1'''
  4 9 2   6 7 2     8 1 6   2 7 6     8 3 4   2 9 4     6 1 8   '''4 3 8'''
