To have infinitely many would require to use also the ℵo successors.
Why don't you use them?
They are outside of FISONs F(n) = {1, 2, 3, ..., n}.
Mais non, there are Aleph_0 FISONs!
Note the universal quantifier in ∀n ∈ UF(n): |ℕ \ {1, 2, 3, ..., n}| =
ℵo
Yeah, what about it? It’s not inside the set to be subtracted.
