Proof step 4 from proof inni-ls-01 (previous step)

i→n(j) ≤ m + n, n→i(m + n) < j, 0 < j ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ i→n(i) ≤ n → ¬ n→i(n) < i

Rule argument

spec: intnat inst: name: inni-le seq: ⊦ i→n(i) ≤ n → ¬ n→i(n) < i subst: [i, n] → [j, m + n] flags: rewrite, current

Additional information

Used terms: j, m + n
