Proof step 2 from proof int2bits-len-abs (previous step)

# int2bits(j) + 1 < # int2bits(~ j) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬(∃ i. j = ~(2 ^ i)) ∧ j < 0 → # int2bits(j) = # int2bits(~ j)
Proof step 4:
¬(¬(∃ i. j = ~(2 ^ i)) ∧ j < 0), # int2bits(j) + 1 < # int2bits(~ j) ⊦

Rule argument

name: int2bits-len-neg-02 rotate: F subst: [j] → [j]

Additional information

Used simplifier rules: ⊦ ¬ m + n < m;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m + n = n + m; Used terms: j
