WebSarrus' rule is useful for third-order determinants only. We rewrite the first two rows while occupying hypothetical fourth and fifth rows, respectively: Once this is done the calculation of the determinant is computed as follows: Multiply the diagonal elements. The descending diagonal from left to right has a sign +, while the descending ... http://teachers.dadeschools.net/rvancol/BlitzerPrecalculusStudentBook/Chapter8/Ch8_Section5.pdf

So the only difference is that we need to know det ( J n). Because J n is a permutation matrix, corresponding to σ n ∈ S n with σ ( i) = n + 1 − i, we have det ( J n) = s g n ( σ n).
