# Automorphisms

## `IsIsomorphic(N1, N2): NfdDck, NfdDck -> BoolElt, Map`

Test whether the regular nearfields $N_1$ and $N_2$ are isomorphic. If they are, return an isomorphism.

## `AutomorphismGroup(N): NfdDck -> GrpPerm, Map`

## `AutomorphismGroup(N): NfdZss -> GrpPerm`

The automorphism group $A$ of the regular nearfield $N$ and a map giving the action of $A$ on $N$.
