pub fn outer_automorphism_order(
degree: usize,
gens: &[Perm],
cap: usize,
) -> Option<u128>Expand description
The order of the outer automorphism group Out(G) = Aut(G)/Inn(G), where the inner automorphisms
Inn(G) ≅ G/Z(G) are those realised by conjugation. Out(G) counts the “exotic” symmetries of the
group not coming from within it. None when out of range.
