But it is only potentially infinite. ℵo successors prevent actual infinity. > you are trying to use a non-set compatible distinction between actual > and potential infinity I prove it. Only finite numbers can be chosen individually. ∀n ∈ ℕ_def: |ℕ \ {1, 2, 3, ..., n}| = ℵo. To have infinitely many would require to use also the ℵo successors. Regards, WM
