Proof step 5 from proof vals-at (previous step)

n ≤ # bytes0, ∀ n0. ¬ # bytes0 ≤ n0 → (mkjavavalues(bytes0)[n0]) = byteval(bytes0[n0]) ∨ bytes0 = [] ⊦ n = 0, (byteval(by) ' + mkjavavalues(bytes0))[n] = byteval(bytes0[n - 1])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
n = m + 1, n ≤ # bytes0, ∀ n0. ¬ # bytes0 ≤ n0 → (mkjavavalues(bytes0)[n0]) = byteval(bytes0[n0]) ∨ bytes0 = [] ⊦ n = 0, (byteval(by) ' + mkjavavalues(bytes0))[n] = byteval(bytes0[m])
