Theorem aprprop 14711

Description: If two structures have the same ring components (properties), df-apr 14700 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 ∈ Ring → ( #r ‘𝐾) = ( #r ‘𝐿))

Proof of Theorem aprprop

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