Proof step 13 from proof bits2bytes-mklist-02 (previous step)

n0 * 8 ≤ 8, ∀ n1. n1 < n0 * 8 → n1 % 8 = 0 → n1 = 0 ∨ bits2bytes(mklist(true, n1)) = mklist(i2b(~1), n1 / 8) ⊦ n0 = 0, n0 = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ n ≠ 0 → (m * n ≤ n ↔ m ≤ 1) subst: [n, m] → [8, n0] rotate: F spec: nat-mult inst: name: leone

Additional information

Used simplifier rules: ⊦ m ≠ 0 → (m ≤ 1 ↔ m = 1); Used terms: 8, n0
