Theorem grucollcld 41386

Description: A Grothendieck universe contains the output of a collection operation whenever its left input is a relation on the universe, and its right input is in the universe. (Contributed by Rohan Ridenour, 11-Aug-2023.)

Hypotheses

Ref	Expression
grucollcld.1	⊢ (𝜑 → 𝐺 ∈ Univ)
grucollcld.2	⊢ (𝜑 → 𝐹 ⊆ (𝐺 × 𝐺))

Assertion

Ref	Expression
grucollcld	⊢ (𝜑 → (𝐹 Coll 𝐴) ∈ 𝐺)

Proof of Theorem grucollcld

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