Proof step 61 from proof eq-leninv (previous step)

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

And obtained the following new goals

Proof step 62:
nσ[m0 + 1] = nσ[n], nσ[m0] + 1 = nσ[n], # nσ = ∞, m0 < m, nσ[m0] < nσ[n], m0 < n, stutf(nσ), nσ[n] < nσ[m], nσ[m0] < nσ[m], n < m → nσ[m] = nσ[n], ∀ m0. n < m0 → nσ[m0] = nσ[n] ⊦ m = 0, nσ[m] = nσ[n], n = 0, nσ[n] = 0, nσ[m] = 0
