Proof step 3 from proof psh-03 (previous step)

⊦ m = m -1 +1, m = 0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: elim seq: ⊦ n ≠ 0 → (n0 = n -1 ↔ n = n0 +1) subst: [n, n0] → [m, n] flags: <rotated> <all paths>

Additional information

Used terms: m, n
