Theorem goalr 35357

Description: If the "Godel-set of universal quantification" applied to a class is a Godel formula, the class is also a Godel formula. Remark: The reverse is not valid for 𝐴 being of the same height as the "Godel-set of universal quantification". (Contributed by AV, 22-Oct-2023.)

Assertion

Ref	Expression
goalr	⊢ ((𝑁 ∈ ω ∧ ∀𝑔𝑖𝑎 ∈ (Fmla‘𝑁)) → 𝑎 ∈ (Fmla‘𝑁))

Distinct variable groups:   𝑖,𝑁   𝑖,𝑎

Allowed substitution hint:   𝑁(𝑎)

Proof of Theorem goalr

Dummy variables 𝑗 𝑥 𝑘 𝑢 𝑣 𝑛 𝑦 are mutually distinct and distinct from all other variables.
