Proof step 67 from proof intshiftrsign-rec-pos (previous step)

0 ≤ i / 2, # uint2bits(i / 2) = 1, 0 ≤ i, i0 < 31, mklist(false, i→n(i0)).first, 0 < i, 1 < i, 0 < i0 ⊦ mklist(false, i→n(i0)) + uint2bits(i / 2) = [], i0 = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 68:
# uint2bits(i / 2) = 1, 0 ≤ i, i0 < 31, mklist(false, i→n(i0)).first, 0 < i, 1 < i, 0 < i0 ⊦ mklist(false, i→n(i0)) + uint2bits(i / 2) = [], i0 = 0

Rule argument

Additional information

Used simplifier rules: i0 ≠ 0, i0 ≤ i ⊦ (* i) ≤ j → (* i0) ≤ j;% ⊦ 0 ≤ i / 2 ↔ ~1 ≤ i;
