New description:
Add the following features to permutation group elements:
{{{
def support(self):
"""
Return the support of ``self`` that is the points that are not
fixed.
"""
def fixed_points(self): ?
...
def cycle_type(self):
"""
Return the cycle type of ``self``.
"""
}}}
Besides, for concistency with the {{{cycle_tuples}}} method, the
{{{cycles}}} method could accept the option singleton. It's questionable
whether we want to have those two very similar methods in the first place.
See also the discussion in #14319.
