Proof step 1 from proof band-011x-neg-03 (conclusion)

⊦ ¬ false ∈ int2bits(i).rest ∧ 0 ≤ i → band(~ j, i) = band(i + 1 - j, i)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
0 ≤ i ⊦ band(~ j, i) = band(i + 1 - j, i), false ∈ int2bits(i).rest

Rule argument

Additional information

Used simplifier rules: ⊦ i ≤ j ∧ 0 ≤ i → 0 ≤ j; (forward)
