Proof step 43 from proof int2bytes-leading-zeros (previous step)

0 ≤ i / 256 ∧ i / 256 ≤ 127, i2b(i / 256) ' = i2b(0) ', int2bytes(i % 256) = bytes0 + i2b(0) ', i2b(0) ∈ int2bytes(i % 256), 0 < i, 0 ≤ i, 255 < i, i / 256 ≤ 127, ∀ bytes, i0. i→n(i0) < i→n(i) → int2bytes(i0) = i2b(0) ' + i2b(0) ' + bytes ∧ 0 ≤ i0 → false ⊦

Additional information

Used simplifier rules: ⊦ 0 < j ∧ 0 ≤ i → 0 ≤ i / j;% ⊦ by ' = by0 ' ↔ by = by0;
