I am sorry... the exact sage-input should of course spell like this:
snip
L = LatinSquare(Matrix([[-1, -1, -1, 6, -1, 0, -1, -1, 9, -1, -1, 8,
11, -1, 4, -1],
[-1, 8, 4, -1, 15, 10, 0, -1, 2, -1, 6, -1, -1, -1, 3, -1],
[-1, -1, 8, -1, -1, 14, 3, 6, -1, -1, 4, 10, 5, 9,
Hello,
while experimenting with some random partial Latin squares I have come
across some squares for which the is_completable() Call seems to loop
indefinitely - i.e. I had to kill sage to abort it (it was not
responding to Ctrl+c) after running for several minutes ... I even once
let it run
