Theorem grpprop 13150

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	|- ( +g ` K ) = ( +g ` L )

Assertion

Ref	Expression
grpprop	|- ( K e. Grp <-> L e. Grp )

Proof of Theorem grpprop

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