Ref Expression
tgrpset  |-  ( ( K  e.  V  /\  W  e.  H )  ->  G  =  { <. (
Base `  ndx ) ,  T >. ,  <. ( +g  `  ndx ) ,  ( f  e.  T ,  g  e.  T  |->  ( f  o.  g
) ) >. } )
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.
