Proof step 127 from proof inv-get-inverse-between (previous step)

# nσ = ∞, nσ[n] = nσ[n1] + 1, stutf(nσ), nσ[n1] < nσ[m1], n1 + m + 1 < n, nσ[n] ≤ nσ[m1], ∀ m. nσ[m] = nσ[n] → ¬ n < m, ∀ m0. m1 < m0 → nσ[m0] = nσ[m1] + 1, ∀ m. nσ[m] = nσ[n1] → ¬ n1 < m ⊦ nσ[m1] = 0, nσ[n1 + m + 1] = nσ[n], n = 0

And obtained the following new goals

Proof step 128:
# nσ = ∞, nσ[n] = nσ[n1] + 1, stutf(nσ), nσ[n1] < nσ[m1], n1 + m + 1 < n, nσ[n] ≤ nσ[m1], ∀ m. nσ[m] = nσ[n] → ¬ n < m, m1 < n → nσ[n] = nσ[m1] + 1, ∀ m0. m1 < m0 → nσ[m0] = nσ[m1] + 1, ∀ m. nσ[m] = nσ[n1] → ¬ n1 < m ⊦ nσ[m1] = 0, nσ[n1 + m + 1] = nσ[n], n = 0
