Proof step 11 from proof bits2bytes-len-02 (previous step)

1 ≤ n, n < 8 ⊦ n = 0, bits = [], (n - 1) / 8 = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ m < n → m / n = 0 subst: [n, m] → [8, n - 1] rotate: F spec: nat-div inst: name: zero-01

Additional information

Used simplifier rules: ⊦ m < 1 ↔ m = 0;% ⊦ ¬ m ≤ n ↔ n < m;%n0 ≤ n ⊦ n - n0 < m ↔ n < m + n0;% ⊦ ¬ m < n ↔ n ≤ m;% ⊦ m ≤ n ∧ n < n0 → m < n0; (forward) Used terms: 8, n - 1
