Theorem isopropd 49018

Description: Two structures with the same base, hom-sets and composition operation have the same isomorphisms. (Contributed by Zhi Wang, 27-Oct-2025.)

Hypotheses

Ref	Expression
sectpropd.1	⊢ (𝜑 → (Homf ‘𝐶) = (Homf ‘𝐷))
sectpropd.2	⊢ (𝜑 → (compf‘𝐶) = (compf‘𝐷))

Assertion

Ref	Expression
isopropd	⊢ (𝜑 → (Iso‘𝐶) = (Iso‘𝐷))

Proof of Theorem isopropd

Dummy variable 𝑓 is distinct from all other variables.
