I would like to know if there is a method to determine how many $n \times n$ Latin square define the same non-commutative group $G$. This is how many representations of $G$ can be obtained from $n$ dimensional Latin squares.
It results that I'm interested on building examples of non-abelian groups to toy with and test how many representations do they have.
(I'm going to assume that the elements of the Latin Square are the elements of the group. If that's not what you want, then make your question clearer.)
For a given group, once you've chosen how you label the rows and columns, the Cayley table is uniquely determined. So if the group has order $n$, it has $(n!)^2$ tables.
