Given a point z in Mobius geometry, how do you find the point w symmetric to z with respect to the unit circle, for example? I understand that (z,z_1,z_2,z_3) = \overline{(w,z_1,z_2,z-3)} (talking about cross ratios) but I'm not sure where to go.
A nudge in the right direction would be appreciated.
