Proof step 12 from proof uint2bits-falsein-01 (previous step)

j = 2 ^ i - 1, j % 2 = 0, 2 ^ i = j + 1, 0 < j, ∀ j0. i→n(j0) < i→n(j) → 0 < j0 → (false ∈ uint2bits(j0).rest ↔ (∀ i. 2 ^ i ≠ j0 + 1)) ⊦ j = 1

And obtained the following new goals

Proof step 13:
(2 ^ i - 1) % 2 = 0, 2 ^ i = (2 ^ i - 1) + 1, 0 < 2 ^ i - 1, ∀ j0. i→n(j0) < i→n(2 ^ i - 1) → 0 < j0 → (false ∈ uint2bits(j0).rest ↔ (∀ i. 2 ^ i ≠ j0 + 1)) ⊦ 2 ^ i - 1 = 1
