Theorem wuncval2 10744

Description: Our earlier expression for a containing weak universe is in fact the weak universe closure. (Contributed by Mario Carneiro, 2-Jan-2017.)

**Hypotheses**
Ref	Expression
wuncval2.f	⊢ 𝐹 = (rec((𝑧 ∈ V ↦ ((𝑧 ∪ ∪ 𝑧) ∪ ∪ 𝑥 ∈ 𝑧 ({𝒫 𝑥, ∪ 𝑥} ∪ ran (𝑦 ∈ 𝑧 ↦ {𝑥, 𝑦})))), (𝐴 ∪ 1_o)) ↾ ω)
wuncval2.u	⊢ 𝑈 = ∪ ran 𝐹

**Assertion**
Ref	Expression
wuncval2	⊢ (𝐴 ∈ 𝑉 → (wUniCl‘𝐴) = 𝑈)

Distinct variable groups: 𝑥,𝑦,𝑧 𝑥,𝐴,𝑦 𝑥,𝑉,𝑦 Allowed substitution hints: 𝐴(𝑧) 𝑈(𝑥,𝑦,𝑧) 𝐹(𝑥,𝑦,𝑧) 𝑉(𝑧)

Proof of Theorem wuncval2 Dummy variables 𝑣 𝑢 𝑤 𝑚 𝑛 are mutually distinct and distinct from all other variables.
