It is possible to choose sub-squares from a 2x2 carpet (see page 4x4 panmagic and each sub-square is (Franklin)
panmagic. It is also possible to swap rows and/or columns 1&3, 2&4, 5&7 and/or 6&8 of each 8x8 Franklin pan
magic square without loosing any magic feature.
[1st] Analysis of an 8x8 panmagic square from the book of Arno van den Essen
In the book “Magische vierkanten: van Lo Shu tot Sudoku” from Arno van den Essen, 2nd print, you can find
on page 152 an 8x8 Franklin panmagic square. By swapping some rows and columns (as mentioned above), you can
simplify the pattern of the square:

[2nd] Analysis of an 8x8 panmagic square on the website of Miguel Angel Amela
On the website www.region.com.ar/amela/franklinsquares/ you can find the square below - an 8x8 Franklin panmagic
square - at structure I. This square can be traced back to a simplified pattern. First row 6&8 and column 5&7 have been
swapped and secondly the coloured digits have been swapped (alternatively).
