Proof step 29 from proof inv-get-inverse-succ (previous step)

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

User applied rule all left

And obtained the following new goals

Proof step 30:
# nσ = ∞, stutf(nσ), ∀ n0. nσ[n0] ≠ n, ∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0], ∃ m. nσ[m] = n ⊦
