And obtained the following new goals

Proof step 77:
bits2int(bitsand(false ' + mklist(true, i→n(i0)), uint2bits(j / 2))) = (j / 2) % 2 ^ i0, j % 2 = 0, 0 < j, 0 ≤ j, 0 ≤ i0, ∀ j0, i. i→n(j0) < i→n(j) → 0 ≤ j0 ∧ 0 ≤ j0 ∧ 0 ≤ i → bits2int(bitsand(false ' + mklist(true, i→n(i)), uint2bits(j0))) = j0 % 2 ^ i ⊦ j = 1, ~1 = i0, (j / 2) % 2 ^ i0 * 2 = j % (2 ^ i0 * 2), bitsand(false ' + mklist(true, i→n(i0)), uint2bits(j / 2)) = []

Additional information

Used simplifier rules: ⊦ i < j ∧ i = i0 → i0 < j; (forward)% ⊦ i % 2 ≠ 1 ∧ 0 < i → i % 2 = 0; (forward)
