Theorem grpprop 13220
Description: If two structures have the same group components (properties), one is a group iff the other one is. (Contributed by NM, 11-Oct-2013.)
Hypotheses
Ref Expression
grpprop.b (Base‘𝐾) = (Base‘𝐿)
grpprop.p (+g𝐾) = (+g𝐿)
Assertion
Ref Expression
grpprop (𝐾 ∈ Grp ↔ 𝐿 ∈ Grp)

Proof of Theorem grpprop
Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
