Proof step 4 from proof py-pw (
previous step
)
pw(user, p, st), px(user, p, st) ⊦ pw(user, meta(p, st))
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 5
:
⊦ pw(user, p, st) ↔ pw(user, meta(p, st)) ∧ px-parent(user, p, st)
Rule argument
spec: <toplevel> name: pw seq: ⊦ pw(user, p, st) ↔ pw(user, meta(p, st)) ∧ px-parent(user, p, st) subst: [st, p, user] → [st, p, user] flags: <all paths>
Additional information
Used terms: st, p, user
