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