Orders that are odd multiples of four are a little more difficult. This is an order twelve pandiagonal magic square with the main Franklin square features. It also has the symmetry feature. This square is symmetrical about the vertical center line. However half rows and half columns with half row totals are not possible in these orders. Instead I’ve produced third rows and third columns with third row totals. Any row or column can be broken into three equal segments and each segment will total 290, one third of the row total. This square doesn’t have imbedded squares.
