Proof step 12 from proof mininv-inverts (previous step)

min(nσ, n + 1) = 1 + min(nσ, n), ⌜min(nσ, n)⌝ < # nσ, n < nσ[min(nσ, n)], ⌜1⌝ + ⌜min(nσ, n)⌝ < # nσ, n < nσ[1 + min(nσ, n)], mon<(nσ), # nσ = ∞ ∨ ¬ nσ[(# nσ).n - 1] < n, ∀ m. ⌜m⌝ < # nσ ∧ n ≤ nσ[m] → min(nσ, n) ≤ m, # nσ = ∞ ∨ n < nσ[(# nσ).n - 1], ∀ m. ⌜m⌝ < # nσ ∧ n < nσ[m] → min(nσ, n) < m ⊦ nσ = [], nσ[min(nσ, n)] = n, nσ[1 + min(nσ, n)] = 0, nσ[min(nσ, n)] = 0

Heuristic quantifier closing applied rule all left

And closed the goal!
