Proof step 9 from proof ubi-io-initial-valid-sqns-h (previous step)

n0 < # apebs, valid-peb(v, m, apebs[n0]), ∀ apebs, v, m. ubi-io-initial(apebs) ∧ n0 ≤ # apebs → valid-sqns(v, m, apebs, n0) = ∅, ∀ n. n < # apebs → ubi-io-peb-initial(apebs[n]) ⊦

User applied rule all left

And obtained the following new goals

Proof step 10:
n0 < # apebs, valid-peb(v, m, apebs[n0]), n0 < # apebs → ubi-io-peb-initial(apebs[n0]), ∀ apebs, v, m. ubi-io-initial(apebs) ∧ n0 ≤ # apebs → valid-sqns(v, m, apebs, n0) = ∅ ⊦
