m m (0.2, 0.6) (0.0, 0.3) m O=(0.0, 0.0) X A plane point group 3m is located at the site (0.0, 0.3). One mirror line is along y-axis (x = 0). An atom A (red) is at (0.2, 0.6) defined by the Cartesian coordinate system. How many equivalent atoms it has due to this plane point group? Calculate the coordinates for all its equivalent atoms. m m (0.2, 0.6) (0.0, 0.3) m O=(0.0, 0.0) X A plane point group 3m is located at the site (0.0, 0.3). One mirror line is along y-axis (x = 0).
