Theorem setrec2v 10015
Description: Version of setrec2 10014 with a disjoint variable condition instead of a nonfreeness hypothesis. (Contributed by Emmett Weisz, 6-Mar-2021.)
Hypotheses
Ref Expression
setrec2.b 𝐵 = setrecs(𝐹)
setrec2.c (𝜑 → ∀𝑎(𝑎 ⊆ 𝐶 → (𝐹‘𝑎) ⊆ 𝐶))
Assertion
Ref Expression
setrec2v (𝜑 → 𝐵 ⊆ 𝐶)
Distinct variable groups:   𝐹,𝑎   𝐶,𝑎
Allowed substitution hints:   𝜑(𝑎)   𝐵(𝑎)
