Hi,
Some remarks and questions...
I guess the order you want is 'degrevlex' as Sage's default order for
multivariate polynomial ring and as the name of your functions
suggest.
Am I wrong ?
At present, I did not modify a lot of things.
A few signs, replaced seq[0] by the smallest item of the sequ

Ok...I got it to work. I forgot to install the java plugin for my
browser. Running jmol strait from sage still doesn't work, but I'm
guessing thats an issue with how I compiled it.

Hello all,
The option "simple=True" to create a simple Cayley graph (as opposed to
a digraph) does not seem to work for me in sage 4.5.3. A small example
follows. What am I doing wrong?
sage: c6=CyclicPermutationGroup(6)
sage: c6.list()
[(), (1,2,3,4,5,6), (1,3,5)(2,4,6),
Hi to all,
Let us say that "reg" is a permutation group. I want to find the
elements of reg that send 12 to 1. Is there a better way to do that (in
one step, say) than:
sage: def f(x): return x(12)==1
:
sage: filter(f,reg.list())
[(1,12)(2,5)(3,4)(6,7)(8,11)(9,10)]
?

Sorry, that was too quick. First determine if 1 and 12 are in the same
"reg" orbit and select an element h of "reg" that sends 12 to 1. Now
determine the stabilizer subgroup of 12 in "reg" and compose with
