Gunter noticed that some of the 264 graeco-latin tours were diagonally
magic.
For example, this one (in octal):
75 32 21 54 47 00 13 66
04 11 62 45 36 23 50 77
61 74 05 22 53 46 37 10
40 07 16 63 72 35 24 51
27 60 73 06 15 52 41 34
56 43 30 17 64 71 02 25
33 26 57 70 01 14 65 42
12 55 44 31 20 67 76 03
The file http://magictour.free.fr/LatinTours.txt contains the 264 tours in
'standard' format, along with the number of diagonally magic squares for
each square.
