I am puzzled by the line art. Is this a variant where the subspaces
are not quadratic ?
If I interpret this in the regular way (dashes denote empty cells):
- - 5 - - 9 - 7 6
- - 2 - - 7 - - -
- - - - - 5 - - -
8 - - - 4 - - - -
9 - - - - - - - 3
- - - - - - - 9 -
- - - - - 8 1 - -
- 2 - - - - 9 - -
- - 8 7 - - - - -
I get the result:
1 3 5 2 8 9 4 7 6
4 6 2 1 3 7 5 8 9
7 8 9 4 6 5 2 3 1
8 5 3 9 4 6 7 1 2
9 4 1 8 7 2 6 5 3
2 7 6 3 5 1 8 9 4
3 9 4 5 2 8 1 6 7
5 2 7 6 1 3 9 4 8
6 1 8 7 9 4 3 2 5
This is really harder than my earlier examples, about 250 ms instead
of 50 :-)
