Proof step 64 from proof eq-leninv (previous step)

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

User applied rule insert lemma

And obtained the following new goals

Proof step 65:
⊦ 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, m, n]

Additional information

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