Proof step 4 from proof notequal-01 (previous step)

s2i(i2s(i)) = s2i(i2s(j)), i2s(i) = i2s(j), ~32768 ≤ i, i ≤ 32767, ~32768 ≤ j, j ≤ 32767 ⊦ i = j

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
~32768 ≤ i, i ≤ 32767 ⊦ s2i(i2s((* i))) = i
Proof step 6:
~32768 ≤ i ∧ i ≤ 32767, i = s2i(i2s(j)), i2s(i) = i2s(j), ~32768 ≤ i, i ≤ 32767, ~32768 ≤ j, j ≤ 32767 ⊦ i = j

Rule argument

name: num-issi rotate: F subst: [i] → [i]

Additional information

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