What size matrix is the level at which the answer is a non-integer for the first time. Then ... what caused it to be a non-integer?

It's not only a function of matrix size but also of its elements, you can get a non-integer determinant even for some 2x2 specific matrix. And I already said in the previous post what causes it: division by some pivot(s) which result in non-exact quotients.
