Concentric magic square
See the previous webpage with a 4x4 in 6x6 magic square, which is almost a concentric magic square.
The 4x4 inlay of a 6x6 concentric magic square must be not panmagic but symmetric.
Use the border of the 4x4 in 6x6 magic square and the Dürer (symmetric) magic square as 4x4 inlay to get a real 6x6 concentric magic square.
