S symmetries are spherical symmetries (rotational symmetries) - meaning that all directions are equal. For complex wave function they become unitary symmetries (SU), or simply symmetries of complex sphere.

Number of dimensions of the sphere (say, 2) gives you symmetry group corresponding to those 2 degrees of freedom - say, complex circle on a plane has SU(2) symmetry.


So, what is the question about those symmetries of rotation?
