Proof step 2 from proof nat2int-04 (previous step)

⊦ n→i(m) < n→i(n) ↔ m < n

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ m < n ↔ n ≤ m
Proof step 4:
⊦ n→i(m) < n→i(n) ↔ ¬ n ≤ m

Rule argument

spec: nat inst: name: lels seq: ⊦ ¬ m < n ↔ n ≤ m subst: [n, m] → [n, m] flags: rewrite
