Proof step 35 from proof bits2bytes-mklist-02 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 36:
⊦ m ≠ 0 → mklist(by, m) = by + mklist(by, m - 1)

Rule argument

seq: ⊦ m ≠ 0 → mklist(by, m) = by + mklist(by, m - 1) subst: [m, by] → [n0, i2b(~1)] rotate: F spec: list-last inst: bytelist name: mk-rec

Additional information

Used simplifier rules: ⊦ by + bytes = by ' + bytes;% ⊦ bytes + bytes0 = bytes + bytes1 ↔ bytes0 = bytes1;% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1; Used terms: n0, i2b(~1)
