Theorem aprprop 14542

Description: If two structures have the same ring components (properties), df-apr 14531 generates the same relation for both of them. (Contributed by Jim Kingdon, 31-May-2026.)

Hypotheses

Ref	Expression
aprprop.b	|- ( Base ` K ) = ( Base ` L )
aprprop.p	|- ( +g ` K ) = ( +g ` L )
aprprop.m	|- ( .r ` K ) = ( .r ` L )

Assertion

Ref	Expression
aprprop	|- ( K e. Ring -> (#r ` K ) = (#r ` L ) )

Proof of Theorem aprprop

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