Proof step 18 from proof bits2bytes-mklist (previous step)

n - 8 ≤ n, n % 8 = 0, 8 < n, ∀ n0. n0 < n → n0 % 8 = 0 → n0 = 0 ∨ bits2bytes(mklist(false, n0)) = mklist(i2b(0), n0 / 8) ⊦ bits2bytes(mklist(false, n - 8)) + i2b(bits2int(lastn(8, mklist(false, n)))) ' = mklist(i2b(0), n / 8)

Additional information

Used simplifier rules: ⊦ m + n = n + m;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m ≤ m + n;%n0 ≤ n ⊦ n - n0 ≤ m ↔ n ≤ m + n0;% ⊦ m < n → m ≤ n;
