Proof step 15 from proof rtc+-unfold-last (previous step)

p*(c, c0), p(c0, b), p(a, c), rtc(n0, c, b) ⊦ p*(a, c0), ∃ c. p*(a, c) ∧ p(c, b)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 16:
⊦ p*(a, b) ∧ p*(b, c) → p*(a, c)

Rule argument

spec: inst: name: rtc-trans seq: ⊦ p*(a, b) ∧ p*(b, c) → p*(a, c) subst: [b, c, a] → [c, c0, a] flags: rewrite, current

Additional information

Used simplifier rules: rtc-one: ⊦ p(a, b) → (¬ p*(a, b) ↔ false); Used terms: c, c0, a
