Theorem tgrpfset 36534
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 (𝐾𝑉 → (TGrp‘𝐾) = (𝑤𝐻 ↦ {⟨(Base‘ndx), ((LTrn‘𝐾)‘𝑤)⟩, ⟨(+g‘ndx), (𝑓 ∈ ((LTrn‘𝐾)‘𝑤), 𝑔 ∈ ((LTrn‘𝐾)‘𝑤) ↦ (𝑓𝑔))⟩}))
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.
