Proof step 47 from proof rg-restr2 (previous step)

∀ m. m ≤ n0 → Ry(m)(s2, s3), Rton(n0)(s1, s2) ⊦ Rton(n0)(s1, s3)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 48:
⊦ Rton(n)(s, s0) ↔ (∀ m. m ≤ n → Ry(m)(s, s0))
Proof step 49:
∀ m. m ≤ n0 → Ry(m)(s2, s3), ∀ m. m ≤ n0 → Ry(m)(s1, s2) ⊦ Rton(n0)(s1, s3)

Rule argument

spec: inst: name: rton-def seq: ⊦ Rton(n)(s, s0) ↔ (∀ m. m ≤ n → Ry(m)(s, s0)) subst: [s0, s, n] → [s2, s1, n0] flags: rewrite, current
