Let $\mathbf{a},$ $\mathbf{b},$ $\mathbf{c}$ be vectors, and let $D$ be the determinant of the matrix whose column vectors are $\mathbf{a},$ $\mathbf{b},$ and $\mathbf{c}.$ Then the determinant of the matrix whose column vectors are $\mathbf{a} \times \mathbf{b},$ $\mathbf{b} \times \mathbf{c},$ and $\mathbf{c} \times \mathbf{a}$ is equal to $k \cdot D^n.$Enter the ordered pair $(k,n).$
