(0.5−3/23/20.5)\begin{pmatrix} 0.5 & -\sqrt{3}/2 \\ \sqrt{3}/2 & 0.5 \end{pmatrix}(0.53/2−3/20.5)
(3/2−0.50.53/2)\begin{pmatrix} \sqrt{3}/2 & -0.5 \\ 0.5 & \sqrt{3}/2 \end{pmatrix}(3/20.5−0.53/2)
(0.53/2−3/20.5)\begin{pmatrix} 0.5 & \sqrt{3}/2 \\ -\sqrt{3}/2 & 0.5 \end{pmatrix}(0.5−3/23/20.5)
(−0.5−3/23/2−0.5)\begin{pmatrix} -0.5 & -\sqrt{3}/2 \\ \sqrt{3}/2 & -0.5 \end{pmatrix}(−0.53/2−3/2−0.5)
