%g displays the acceptance formula, but we have no way to display the acceptance "name" (e.g. "parity odd even 7" instead of a huge formula) if it exists.
I suggest introducing
%[n]gto display the "full name" ("parity odd even 7" or "Rabin 4")
%[a]gto display just the acceptance name ("parity" or "Rabin")
I'd suggest to use "other N" for naming unknown acceptance conditions with N sets instead of the empty string.
This way, it's easier to use
... | autfilt -o '%[a]g' to bin automata in different files according to their acceptance.
