Dear Naaaaaaaaaaaaathan,
It'd sure be great to have automorphism groups of graphs start their symbol
sets back at 0! And perhaps optionally use vertex labels.
sage: G = SymmetricGroup([0, 1, 2]); G
Symmetric group of order 3! as a permutation group
sage: G.domain()
{0, 1, 2}
sage: G = SymmetricGroup(['dog', 'cat', 'fish']); G
Symmetric group of order 3! as a permutation group
sage: G.domain()
{'dog', 'cat', 'fish'}
I have not investigated the following yet. I thought tuples being hashable
was sufficient.
sage: G = SymmetricGroup([(1,0), (0,1)])
...
