Proof step 5 from proof ushort-pos-01 (previous step)

i < 65536, 0 ≤ i, 0 ≤ s2i(i2s(i)) ⊦ s2i(i2s(i)) = i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
~32768 ≤ i, i ≤ 32767 ⊦ s2i(i2s((* i))) = i
Proof step 7:
¬(~32768 ≤ i ∧ i ≤ 32767), i < 65536, 0 ≤ i, 0 ≤ s2i(i2s(i)) ⊦ s2i(i2s(i)) = i

Rule argument

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