Yes that is my claim. But I cannot give> an upper limit, because the finite numbers have no upper limit. This> is called potentially infinite.Being potentially infinite is like being "a little bit pregnant". In the real world and in the mathematical world, pregnancy and infiniteness are on and off characteristics, with no middle ground between being and not being.  > >> > > There it has meanwhile turned out ...

In a Complete Infinite Binary Tree the set of "levels" bijects with |N which also does NOT contain an "omegath" member.--
