Theorem tgrpfset 36032

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 e. V -> ( TGrp ` K ) = ( w e. H |-> { <. ( Base ` ndx ) , ( ( LTrn ` K ) ` w ) >. , <. ( +g ` ndx ) , ( f e. ( ( LTrn ` K ) ` w ) , g e. ( ( LTrn ` K ) ` w ) |-> ( f o. 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.
