Ref Expression
erngset-rN ((𝐾𝑉𝑊𝐻) → 𝐷 = {⟨(Base‘ndx), 𝐸⟩, ⟨(+g‘ndx), (𝑠𝐸, 𝑡𝐸 ↦ (𝑓𝑇 ↦ ((𝑠𝑓) ∘ (𝑡𝑓))))⟩, ⟨(.r‘ndx), (𝑠𝐸, 𝑡𝐸 ↦ (𝑡𝑠))⟩})
Distinct variable groups:   𝑓,𝑠,𝑡,𝐾   𝑓,𝑊,𝑠,𝑡
Allowed substitution hints:   𝐷(𝑡,𝑓,𝑠)   𝑇(𝑡,𝑓,𝑠)   𝐸(𝑡,𝑓,𝑠)   𝐻(𝑡,𝑓,𝑠)   𝑉(𝑡,𝑓,𝑠)

Proof of Theorem erngset-rN
Dummy variable 𝑤 is distinct from all other variables.
