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  |-  ( +g  `  K )  =  ( +g  `  L )
Assertion
Ref Expression
mndprop  |-  ( K  e.  Mnd  <->  L  e.  Mnd )

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