Proof step 11 from proof int2bits-true (previous step)

j < 0 ⊦ j = ~1, bitsinvert(uint2bits(~ j)) +1 = [], false ∈ bitsinvert(uint2bits(~ j)) +1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 12:
⊦ 1 < i → false ∈ bitsinvert(uint2bits(i)) +1

Rule argument

name: uint2bits-falsein rotate: F subst: [i] → [~ j]

Additional information

Used simplifier rules: ⊦ i < ~ j ↔ i + j < 0;% ⊦ i + (* j) < (* j0) ↔ i < j0 - j;% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ i < 0 → (~1 ≤ i ↔ i = ~1);% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used terms: ~ j
