I do not know (and I do not bother to know) how to write such a
function since the function has already been implemented (nicely) in
the IMS (IMTEK Mathematica Supplement) package, which is an *open
source* package. *Open source* means that the source code is available
free of charge.

Therefore, if I were you, I would download the IMS package, install it
on my machine, then I would play around with the function *ExactCover*
to get acquainted with it (the documentation have some examples about
Latin squares) and I would look at its code (which is provided with
package) if I wish.

The IMS main web page contains links to the download area as well as
directions to install the package.
