Wrong. |ℕ| is a fixed number.
However,
ℕ is the set of all 'fixed' (finite) ordinals.
⎛ Assume ℕ is 'fixed'.|ℕ| = ω-1.
⎜
⎜ A 'fixed' ordinal ⟦0,𝔑⦆ the size of ℕ exists.
⎜ #⟦0,𝔑⦆ = #ℕω
⎜
⎜ ⟦0,𝔑+1⦆ is 'fixed', too.
⎜ ⟦0,𝔑+1⦆ ⊆ ℕNo.
Therefore,If it were not, then it would not be a set.
ℕ is not 'fixed'.
