Proof step 27 from proof int2bits-2pot-04 (previous step)

mklist(false, i→n(i)) ≠ [] ∧ (¬ mklist(false, i→n(i)).first) ∈ bitsinvert(uint2bits(~ j)) +1, 0 < i, 0 < 2 ^ i, j < 2 ^ i, j < 0, j + 1 < 2 ^ i, j < i, j * 2 ^ i < i, j + 1 < i ⊦ sgn(bitsinvert(uint2bits(~ j)) +1) + mklist(false, i→n(i)) = int2bits(j) + mklist(false, i→n(i)), j = 0, i = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 28:
(¬ mklist(false, i→n(i)).first) ∈ bitsinvert(uint2bits(~ j)) +1, 0 < i, 0 < 2 ^ i, j < 2 ^ i, j < 0, j + 1 < 2 ^ i, j < i, j * 2 ^ i < i, j + 1 < i ⊦ j = 0, i = 0, sgn(bitsinvert(uint2bits(~ j)) +1) = int2bits(j)

Additional information

Used simplifier rules: ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i→n(i) = 0 ↔ i = 0;% ⊦ mklist(boolvar, m) = [] ↔ m = 0;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ bits + bits0 = bits1 + bits0 ↔ bits = bits1;
