Note that this makes t an involutive antiautomorphism of G.
The supercharacter theory is also independent of the choice of subfield of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]; that is, if F is any subfield of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and [dagger] is an antiautomorphism of g when viewed as an F-algebra, we get the same supercharacter theory as by considering g as an [F.
The antiautomorphism [dagger] as defined above restricts to an antiautomorphism of [U.
t]J defines an antiautomorphism of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] if we consider [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] as an [F.
