Proof step 73 from proof inv-inverts-leq (previous step)

# nσ = ⌜m⌝ + ⌜1⌝ , max∞(λ n0. ¬ m < n0 ∧ nσ[n0] = nσ[n]) = ⌜n1⌝ , n1 < n, n1 < m, stutf(nσ), nσ[n] ≤ nσ[m], n ≤ m ⊦ max∞(λ n0. ¬ m < n0 ∧ nσ[n0] = nσ[n]) = ∞

And obtained the following new goals

Proof step 74:
# nσ = ⌜m⌝ + ⌜1⌝ , max∞(λ n0. ¬ m < n0 ∧ nσ[n0] = nσ[n]) = ⌜n1⌝ , n1 < m, n1 < n, stutf(nσ), nσ[n] ≤ nσ[m], n ≤ m ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ ⌜m⌝ ≠ ∞; (s)%fle: ⊦ m < n ∧ n ≤ n0 → m < n0; (forward) from specification nat
