Constructing Cayley Graphs

edit

I am having confusions in constructing a Cayley Graph in Sage Math. Say, I want to construct the Cayley graph on the Symmetric Group $S_4$ with respect to the generating set consisting of all transpositions, what code do I use.

I tried the following minimal code:

G = SymmetricGroup(4)
CG = G.cayley_graph(generators=[PermutationGroupElement([1, 2]),
                                PermutationGroupElement([1, 3]),
                                PermutationGroupElement([1, 4]),
                                PermutationGroupElement([2, 3]),
                                PermutationGroupElement([2, 4]),
                                PermutationGroupElement([3, 4])])
CGU = CG.to_undirected()
CGU.show()

But, I get the error

    501         # a valid permutation (else segfaults, infinite loops may occur).
    502         if not is_valid_permutation(self.perm, self.n):
--> 503             raise ValueError("invalid data to initialize a permutation")
    504 
    505         # This is more expensive

ValueError: invalid data to initialize a permutation

How do I rectify the code so as to produce my desired Cayley Graph. Any suggestions?
