You said that the Binary Tree, when constructed from its FISONs, does not contain their suprema.
You said that the list 1 1, 2 1, 2, 3 ... does not contain a line |N, but this list contains an infinite sequence of finite unions.
Why is the result of infinitely many unions different from the result of an infinite union?

Any one? Does this include the line n+1 if I remove line n? Then it depends on your answers.
But for any fixed n, yes, lines n+1 ... remain and with them every natural number.
