Proof step 4 from proof short-nle (previous step)

s2i(sho) < 0, ¬ ~32769 < s2i(sho) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ i < j ↔ i +1 = j ∨ i +1 < j

Rule argument

seq: ⊦ i < j ↔ i +1 = j ∨ i +1 < j subst: [j, i] → [s2i(sho), ~32769] rotate: F spec: int-basic1 inst: name: lsrec

Additional information

Used simplifier rules: short-min-03: ⊦ s2i(sho) ≤ ~32768 ↔ s2i(sho) = ~32768;% ⊦ ¬ i < j ↔ j ≤ i; Used terms: s2i(sho), ~32769
