Comment(by saliola):
Replying to [comment:5 dmharvey]:
> OK, can I just clarify that the problem with the original code is that
the GAP Representative function doesn't return a canonical representative?
i.e. if you start with two different group elements in the same class,
convert them to classes and then ask for their Representative, you might
get different answers?
That is correct, here's an illustration.
{{{
sage: G = SymmetricGroup(3)
sage: g = G((1,2))
sage: h = G((2,3))
sage: gap(G).ConjugacyClass(h).Representative()
(2,3)
sage: gap(G).ConjugacyClass(g).Representative()
(1,2)
sage: gap(G).ConjugacyClass(g) == gap(G).ConjugacyClass(h)
True
}}}
