Theorem caovordd

Description: Convert an operation ordering law to class notation. (Contributed by Mario Carneiro, 30-Dec-2014)

Ref Expression
Hypotheses caovordg.1 ⊢ φ ∧ x ∈ S ∧ y ∈ S ∧ z ∈ S → x R y ↔ z F x R z F y
caovordd.2 ⊢ φ → A ∈ S
caovordd.3 ⊢ φ → B ∈ S
caovordd.4 ⊢ φ → C ∈ S
Assertion caovordd ⊢ φ → A R B ↔ C F A R C F B

Proof
