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)
tgrpset.g 𝐺 = ((TGrp‘𝐾)‘𝑊)
Assertion
Ref Expression
tgrpset ((𝐾𝑉𝑊𝐻) → 𝐺 = {⟨(Base‘ndx), 𝑇⟩, ⟨(+g‘ndx), (𝑓𝑇, 𝑔𝑇 ↦ (𝑓𝑔))⟩})
Distinct variable groups:   𝑓,𝑔,𝐾   𝑇,𝑓,𝑔   𝑓,𝑊,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.
