Let $\displaystyle a$ be the length of a side of a square OABC with O being the origin. Its side OA makes an acute angle $\displaystyle \alpha$ with the positive $\displaystyle x$-axis and the equations of its diagonals are $\displaystyle (\sqrt{3}+1) x+(\sqrt{3}-1) y=0$ and $\displaystyle (\sqrt{3}-1) x-(\sqrt{3}+1) y+8 \sqrt{3}=0$. Then $\displaystyle a^2$ is equal to
