Theorem mndprop 13025
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 (+g𝐾) = (+g𝐿)
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.
