Analysis of the (basic patterns of the) 8x8 Franklin panmagic square
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 men-
tioned 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).

It appears to be a new basic pattern but it is in fact the basic pattern of a sub-square on the 2x2 carpet
of the already known basic pattern (see below).
