Description: The translation group for a fiducial co-atom 𝑊. (Contributed by NM, 5-Jun-2013.)

Hypotheses

Ref	Expression
tgrpset.h	⊢ 𝐻 = (LHyp‘𝐾)
tgrpset.t	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)

Assertion

Ref	Expression
tgrpset	⊢ ((𝐾 ∈ 𝑉 ∧ 𝑊 ∈ 𝐻) → 𝐺 = {⟨(Base‘ndx), 𝑇⟩, ⟨(+g‘ndx), (𝑓 ∈ 𝑇, 𝑔 ∈ 𝑇 ↦ (𝑓 ∘ 𝑔))⟩})

Allowed substitution hints:   𝐺(𝑓,𝑔)   𝐻(𝑓,𝑔)   𝑉(𝑓,𝑔)

Proof of Theorem tgrpset

Dummy variable 𝑤 is distinct from all other variables.
