swapfval.d	⊢ (𝜑 → 𝐷 ∈ 𝑉)
swapfval.s	⊢ 𝑆 = (𝐶 ×c 𝐷)

Assertion

Ref	Expression
swapfval	⊢ (𝜑 → (𝐶 swapF 𝐷) = ⟨(𝑥 ∈ 𝐵 ↦ ∪ ◡{𝑥}), (𝑢 ∈ 𝐵, 𝑣 ∈ 𝐵 ↦ (𝑓 ∈ (𝑢𝐻𝑣) ↦ ∪ ◡{𝑓}))⟩)

Distinct variable groups:   𝑢,𝐵,𝑣,𝑥   𝑢,𝐶,𝑣   𝑢,𝐷,𝑣   𝑓,𝐻,𝑢,𝑣   𝑢,𝑆,𝑣   𝜑,𝑢,𝑣   𝑥,𝑓

Allowed substitution hints:   𝜑(𝑥,𝑓)   𝐵(𝑓)   𝐶(𝑥,𝑓)   𝐷(𝑥,𝑓)   𝑆(𝑥,𝑓)   𝑈(𝑥,𝑣,𝑢,𝑓)   𝐻(𝑥)   𝑉(𝑥,𝑣,𝑢,𝑓)

Proof of Theorem swapfval

Dummy variables 𝑏 𝑐 𝑑 ℎ 𝑠 are mutually distinct and distinct from all other variables.
