Proof step 68 from proof inv-get-inverse (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 69:
# nσ = ⌜n1⌝ , max∞(λ n0. n0 < n1 ∧ nσ[n0] = n) = ∞, stutf(nσ), n ≤ nσ[n1 - 1] ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ ⌜m⌝ ≠ ∞; (s)% ⊦ ⌜m⌝ < ⌜n⌝ ↔ m < n; (s)
