Proof step 25 from proof lst-02 (
previous step
)
i0 < j -1 ∨ j -1 < i0 ⊦ i0 +1 = j, i0 +1 < j, j < i0 +1
Heuristic elimination applied rule insert elim lemma
And obtained the following new goals
Proof step 26
:
⊦ i = j -1 ↔ j = i +1
Proof step 27
:
j = i +1, i0 < i ∨ i < i0 ⊦ i0 +1 = j, i0 +1 < j, j < i0 +1
Rule argument
spec: int-basic1 inst: name: elim-pred seq: ⊦ i = j -1 ↔ j = i +1 subst: [j, i] → [j, i] flags: rewrite, current
Additional information
Used terms: j, i
