Theorem mndprop 13514

Description: If two structures have the same group components (properties), one is a monoid iff the other one is. (Contributed by Mario Carneiro, 11-Oct-2013.)

Hypotheses

Ref	Expression
mndprop.b	⊢ (Base‘𝐾) = (Base‘𝐿)
mndprop.p	⊢ (+g‘𝐾) = (+g‘𝐿)

Assertion

Ref	Expression
mndprop	⊢ (𝐾 ∈ Mnd ↔ 𝐿 ∈ Mnd)

Proof of Theorem mndprop

Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
