When you gave this example against my contention that
every club must be final:

How can membership in A not preclude membership in any club
and at the same time membership in D preclude membership in A?
That's where I got the idea that maybe by "preclusion" you
meant something like the rules of the club. Obviously Club A
can have no precluding rule and D preclude its members from
being members of A. I take it that is not what you meant?

So, how is it possible that some club is not final and
at the same time final clubs are well defined? Can we
have an example?
