Proof step 3 from proof restrict-union-inter-empty-left (
previous step
)
⊦ ∀ adr. adr ∈ (as0 | n) ∩ ((as1 \ (as1 | n)) ∪ as2) ↔ adr ∈ (as0 | n) ∩ as2
Heuristic simplifier applied rule simplifier
And obtained the following new goals
Proof step 4
:
⊦ adr ∈ (as0 | n) ∩ ((as1 \ (as1 | n)) ∪ as2) ↔ adr ∈ (as0 | n) ∩ as2
Rule argument
