Bug: Cayley Graph

[M. Fix]

Hello-
I input the following:

sage: s1 = SymmetricGroup(1)
sage: s = s1.cayley_graph()
sage: s.vertices()
[]

Shouldn't the set of vertices have one element in it for the
identity? s1 reports this element, but as shown the graph does not.
I suppose this is trivial, but it seems like it should be fixed at
some point. I am, however, still fairly new to SAGE, and could easily
be missing something. Any thoughts on this?

Hi,

Looks like the identity is not printed or the constructor for
cayley_graph() gets that case wrong. For s2 the identity is there,
i.e.

sage: s2g.vertices()
[(), (1,2)]

Somebody more familiar with the code ought to figure out what is going
on and open a ticket.

Cheers,

Michael

Hi,

I have made this

http://trac.sagemath.org/sage_trac/ticket/3070

and assigned it to boothy, so he will get an email about it ;)

Cheers,
