The motivation to use this wording was to inhibit that someone finds a non-Latin square with exactly the already shown value of the maximum Latin-square determinant. Nobody could give me an answer of the question "is it possible to construct a non-Latin square with determinant 929587995"?. All possible determinant values of 9x9 Latin squares are known from an (yet unpublished) enumeration expanding the data given by Brendan McKay. I can provide more information after the end of the submission period. If you should find a Latin square with determinant in the range [loophole barrier, record] I'm extremely curious to see ist.
