Given an (irreducible complex) character of a finite group the following three construction all yield another irreducible character of the same degree:
- multiplying by a degree 1 character
- applying an outer automorphism
- taking a Galois conjugate
Note that 2) and 3) never change the set of character values, they just permute the list.
The degree five characters of $ A_6 $ are not Galois conjugate but are related by an outer automorphism. The two degree $ 16 $ characters of $ M_{11} $ are not related by an outer automorphism but are Galois conjugate.
What is an example of a finite group $ G $ and two distinct irreducible characters of $ G $ which have the same character values but are not related by any combination of the three constructions given above?
This is in some sense a follow up question to
Same character values iff related by outer automorphism, for perfect groups
