Theorem 2oppccomf 16983
Description: The double opposite category has the same composition as the original category. Intended for use with property lemmas such as monpropd 16995. (Contributed by Mario Carneiro, 3-Jan-2017.)
Hypothesis
Ref Expression
oppcbas.1 𝑂 = (oppCat‘𝐶)
Assertion
Ref Expression
2oppccomf (compf𝐶) = (compf‘(oppCat‘𝑂))

Proof of Theorem 2oppccomf
Dummy variables 𝑓 𝑔 𝑥 𝑦 𝑧 are mutually distinct and distinct from all other variables.
