Proof step 103 from proof inv-get-inverse-between (previous step)

# nσ = ∞, nσ[n] = nσ[m0], m0 < n, ∞.n + m + 1 < max∞(λ n0. nσ[n0] = nσ[m0] + 1).n, nσ[m0] < nσ[m1], m1 < n, stutf(nσ), m0 ≤ m1, ∀ m0. m1 < m0 → nσ[m0] = nσ[m1] + 1 ⊦ nσ[∞.n + m + 1] = nσ[m0] + 1

User applied rule insert lemma

And obtained the following new goals

Proof step 104:
⊦ mon≤(nσ) ∧ m ≤ n ∧ ⌜n⌝ < # nσ → nσ[m] ≤ nσ[n]

Rule argument

spec: <toplevel> name: monle-leq seq: ⊦ mon≤(nσ) ∧ m ≤ n ∧ ⌜n⌝ < # nσ → nσ[m] ≤ nσ[n] subst: [nσ, m, n] → [nσ, m1, n]

Additional information

Used simplifier rules: stutf-monle: ⊦ stutf(nσ) → (mon≤(nσ) ↔ true);% ⊦ m < n → m ≤ n; (s)% ⊦ ⌜m⌝ < ∞; (s)% ⊦ m < n → (n ≤ m ↔ false); (s) Used terms: nσ, m1, n
