Proof step 28 from proof bits2bytes-mklist (previous step)

8 ≠ 0, 1 < n0, ∀ n1. n1 < n0 * 8 → n1 % 8 = 0 → n1 = 0 ∨ bits2bytes(mklist(false, n1)) = mklist(i2b(0), n1 / 8) ⊦ bits2bytes(mklist(false, n0 * 8 - 8)) + i2b(0) ' = mklist(i2b(0), n0), (n0 * 8 - 8) % 8 = 0, n0 = 0

And obtained the following new goals

Proof step 29:
∀ n1. n1 < n0 * 8 → n1 % 8 = 0 → n1 = 0 ∨ bits2bytes(mklist(false, n1)) = mklist(i2b(0), n1 / 8) ⊦ bits2bytes(mklist(false, n0 * 8 - 8)) + i2b(0) ' = mklist(i2b(0), n0), (n0 * 8 - 8) % 8 = 0, n0 = 1, n0 = 0

Additional information

Used simplifier rules: ⊦ 1 < m ↔ ¬(m = 0 ∨ m = 1);% ⊦ m < n → n ≠ 0;
