Proof step 46 from proof int2bytes-leading-zeros (previous step)

int2bytes(i % 256) = bytes0 + i2b(0) ', b2i(i2b(i / 256)) = b2i(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 ⊦

And obtained the following new goals

Proof step 47:
int2bytes(i % 256) = bytes0 + i2b(0) ', b2i(i2b(i / 256)) = 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 ⊦
