Theorem oiiso2 9029
 Description: The order isomorphism of the well-order 𝑅 on 𝐴 is an isomorphism onto ran 𝑂 (which is a subset of 𝐴 by oif 9028). (Contributed by Mario Carneiro, 25-Jun-2015.)
Hypothesis
Ref Expression
oicl.1 𝐹 = OrdIso(𝑅, 𝐴)
Assertion
Ref Expression
oiiso2 ((𝑅 We 𝐴𝑅 Se 𝐴) → 𝐹 Isom E , 𝑅 (dom 𝐹, ran 𝐹))

Proof of Theorem oiiso2
Dummy variables 𝑢 𝑡 𝑣 𝑥 𝑗 𝑤 𝑧 𝑓 𝑖 𝑟 𝑠 𝑦 are mutually distinct and distinct from all other variables.
