Proof step 4 from proof weakmon-lem (previous step)

∀ m. ii(m) ≤ ii(m0), ∀ n. ii(n) ≤ ii(n + 1) ⊦ ∃ m. n ≤ ii(m), ∃ n0. ∀ m. n0 ≤ m → ii(m) = ii(n0)

User applied rule exists right

And obtained the following new goals

Proof step 5:
∀ m. ii(m) ≤ ii(m0), ∀ n. ii(n) ≤ ii(n + 1) ⊦ ∃ m. n ≤ ii(m), ∀ m. m0 ≤ m → ii(m) = ii(m0)
