Then you are wrong.
Every inductive set is infinite.
Some infinite sets, such as E(137),
are not inductive.>That is irrelevant.
Also,
some inductive sets, such as ℝ,
are not minimal.inductive.
The set of useless FISONs is inductive and therefore infinite. No FISON can change the assumption U(A(n)) = ℕ. Therefore every FISON can be omitted. ==> { } = ℕ.
