In every ennumeration it will be the 99th set, but in different
ennumerations it will be usually a different one of the original set.

Only if their overall ordering is required to be a well ordering.
But if one bijects the naturals with the members of an open interval of
rationals and imposes the ordering of those rationals back onto the
naturals, for the resulting ordered set of naturals it is no longer true.

Whenever there is a formidableborder like that between Wolkenmuekenheim
and the world, there will be considerable questions about everything
until it has been made clear from which side of that border one is
