Proof step 167 from proof int2bytes-rec-neg-02 (previous step)

2 ^ (i * 8) = 0, # (mklist(false, i→n(i * 8) + 1 - # int2bits(j % 0)) + int2bits(j % 0)).rest % 8 = 0, j < 0, 0 < j % 0, 0 < i, # int2bits(j % 0) ≤ i→n(i * 8) + 1 ⊦ (mklist(false, i→n(i * 8) + 1 - # int2bits(j % 0)) + int2bits(j % 0)).rest = [], bits2bytes((mklist(false, i→n(i * 8) + 1 - # int2bits(j % 0)) + int2bits(j % 0)).rest) = fix(i→n(i) + 1, int2bytes(j % 0)).rest

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 168:
⊦ 0 ≤ j → 2 ^ j ≠ 0

Rule argument

seq: ⊦ 0 ≤ j → 2 ^ j ≠ 0 subst: [j] → [i * 8] rotate: F spec: int-pot inst: name: two-zero

Additional information

Used simplifier rules: ⊦ 0 < i → (0 ≤ i * j ↔ 0 ≤ j);% ⊦ i * j * j0 = (i * j) * j0;% ⊦ i * j = j * i; Used terms: i * 8
