Theorem tgrpfset 41190

Description: The translation group maps for a lattice 𝐾. (Contributed by NM, 5-Jun-2013.)

Hypothesis

Ref	Expression
tgrpset.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
tgrpfset	⊢ (𝐾 ∈ 𝑉 → (TGrp‘𝐾) = (𝑤 ∈ 𝐻 ↦ {⟨(Base‘ndx), ((LTrn‘𝐾)‘𝑤)⟩, ⟨(+g‘ndx), (𝑓 ∈ ((LTrn‘𝐾)‘𝑤), 𝑔 ∈ ((LTrn‘𝐾)‘𝑤) ↦ (𝑓 ∘ 𝑔))⟩}))

Distinct variable groups:   𝑤,𝐻   𝑓,𝑔,𝑤,𝐾

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

Proof of Theorem tgrpfset

Dummy variable 𝑘 is distinct from all other variables.
