Proof step 6 from proof notequal (previous step)

~128 ≤ i ∧ i ≤ 127, i = b2i(i2b(j)), i2b(i) = i2b(j), ~128 ≤ i, i ≤ 127, ~128 ≤ j, j ≤ 127 ⊦ i = j

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
~128 ≤ i, i ≤ 127 ⊦ b2i(i2b((* i))) = i

Rule argument

name: num-ibbi rotate: F subst: [i] → [j]

Additional information

Used simplifier rules: ibi: ⊦ i2b(b2i(by)) = by;%i0 ≠ 0, i0 ≤ i ⊦ (* i) ≤ j → (* i0) ≤ j;%j0 ≠ 0, j ≤ j0 ⊦ i ≤ (* j) → i ≤ (* j0); Used terms: j
