Proof step 3 from proof restrict-in-empty (previous step)

range ri | n = ∅, @(n, m0, m1) ∈ ri ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: set-basic, inst: node-store name: Extension seq: ⊦ as = as0 ↔ (∀ adr. adr ∈ as ↔ adr ∈ as0) subst: [as0, as] → [∅, range ri | n] flags: <all paths>

Additional information

Used terms: ∅, range ri | n
