Proof step 31 from proof inv-get-inverse (previous step)

# nσ = ∞, stutf(nσ), ∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0], ∀ nσ0. # nσ0 ≠ ∞ ∨ ¬ stutf(nσ0) ∨ ¬(∀ n1. nσ0[n1] ≠ n0) ∨ ¬(∀ m. ∃ m0. m < m0 ∧ nσ0[m] < nσ0[m0]), ∀ n. nσ[n] ≠ n0 + 1 ⊦

User applied rule all left

And obtained the following new goals

Proof step 32:
# nσ = ∞, stutf(nσ), ∀ n. nσ[n] ≠ n0 + 1, ∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0], # nσ ≠ ∞ ∨ ¬ stutf(nσ) ∨ ¬(∀ n1. nσ[n1] ≠ n0) ∨ ¬(∀ m. ∃ m0. m < m0 ∧ nσ[m] < nσ[m0]) ⊦
