Hi guys,
I have the following setting: Given a finite subgroup G of GL_\C(n) of
order k, acting on C[x_1,...,x_n] by multiplication with (potenz of a )
k-th root of unity.
yea, that's nearly what I am looking for. Is it possible to consider a
weighted group action too?
e.g. If \xi is of order n and \xi a n-th root of unity.
g (p_1,\dots, p_n) \to (\xi^a_1 p1 , dots, \xi^a_n p_n)?
s.t. \sum a_i = n?

Hi Johannes,
thnx,
this looks nice. I'll have a deeper look at it in the next days.

One thing to watch out for is that the generators returned by
automorphism_group contain symbols that may not be the actual vertices. I
realised this once after several frustrating hours of bizarre results from
my program. I'm not sure if this is still the case in recent versions.
Yep. I

Well, you can call GAP, e.g. as follows:
sage: gap(Orbit(+str(ag._gap_())+,[1,2,7],OnSets);)
[ [ 1, 2, 7 ], [ 1, 2, 3 ], [ 1, 6, 9 ], [ 2, 3, 4 ], [ 3, 4, 10 ],
[ 1, 6, 8 ], [ 3, 4, 8 ], [ 4, 9, 10 ], [ 4, 7, 9 ], [ 5, 8, 10 ],
[ 2, 5, 7 ], [ 5, 6, 8 ], [ 3, 5, 8 ], [ 4, 6, 9 ], [ 5, 7,

Hellooo everybody !!!
I would like to play with groups in Sage but I do not know how. I
actually get my groups from a graph in the following way :
sage: g = graphs.PetersenGraph()
sage: ag = g.automorphism_group()
