Proof step 76 from proof inv-inverts-leq (previous step)

# nσ = ⌜m⌝ + ⌜1⌝ , nσ[n1] = nσ[n], n1 < n, n1 < m, stutf(nσ), n ≤ m, nσ[n] ≤ nσ[m], ∀ m0. ¬ m < m0 ∧ nσ[m0] = nσ[n] → ¬ n1 < m0 ⊦ m < n1

And obtained the following new goals

Proof step 77:
# nσ = ⌜m⌝ + ⌜1⌝ , nσ[n1] = nσ[n], n1 < m, n1 < n, stutf(nσ), nσ[n] ≤ nσ[m], n ≤ m, ∀ m0. ¬ m < m0 ∧ nσ[m0] = nσ[n] → ¬ n1 < m0 ⊦
