I just finished the graeco-latin torus tours program !
I ran a quick test on 6x6 on the 4 possible tours (a1-a2, a1-a4, a1-b3 and
a1-c4), and found no solution in 0 second.

On the 8x8 board, there are 6 possible start-end tours on a torus:
a1-a2
a1-a4
a1-b3
a1-b5
a1-c4
a1-d5

I'll publish the program soon after some preliminary tests.
