Description: The predicate "is a closed operation". (Contributed by AV, 13-Jan-2020.)
Assertion
Ref Expression
iscllaw (( 𝑉𝑀𝑊) → ( clLaw 𝑀 ↔ ∀𝑥𝑀𝑦𝑀 (𝑥 𝑦) ∈ 𝑀))
Distinct variable groups:   𝑥,𝑀,𝑦   𝑥, ,𝑦
Allowed substitution hints:   𝑉(𝑥,𝑦)   𝑊(𝑥,𝑦)

Proof of Theorem iscllaw
Dummy variables 𝑚 𝑜 are mutually distinct and distinct from all other variables.
