Proof step 8 from proof lebs-write-subseteq (previous step)

@(m0, m3, m4) ∈ ri[key, @(m, m1, m2)], ri.lebs ⊆ dom gstore ⊦ m0 = m, m0 ∈ gstore

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ ns ⊆ ns0 ↔ (∀ n. n ∈ ns → n ∈ ns0)
Proof step 10:
@(m0, m3, m4) ∈ ri[key, @(m, m1, m2)], ∀ n. n ∈ ri.lebs → n ∈ dom gstore ⊦ m0 = m, m0 ∈ gstore

Rule argument

spec: set-basic, inst: nat-set name: Subset seq: ⊦ ns ⊆ ns0 ↔ (∀ n. n ∈ ns → n ∈ ns0) subst: [ns0, ns] → [dom gstore, ri.lebs] flags: <all paths>

Additional information

Used terms: dom gstore, ri.lebs
