Proof step 17 from proof inv-get-inverse-succ (previous step)

∀ n0. ∃ n1. n0 < n1 ∧ nσ[n1] = n, ∀ n. ∃ m. nσ[m] = n, # nσ = ∞, stutf(nσ), ∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0] ⊦

And obtained the following new goals

Proof step 18:
∃ n1. 0 < n1 ∧ nσ[n1] = n, ∀ n0. ∃ n1. n0 < n1 ∧ nσ[n1] = n, ∀ n. ∃ m. nσ[m] = n, # nσ = ∞, stutf(nσ), ∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0] ⊦
