14. If one of the vertices of the square circumscribing the circle $| z - 1 | = \sqrt { } 2$ is $2 + \sqrt { } 3 \mathrm { i }$. Find the other vertices of square.
The tangent to the curve $y = x ^ { 2 } + 6$ at the point $P ( 1,7 )$ touches the circle $x ^ { 2 } + y ^ { 2 } + 16 x + 12 y + c = 0$ at a point $Q$. Then the coordinates of $Q$ are
