ltrnset  |-  ( ( K  e.  B  /\  W  e.  H )  ->  T  =  { f  e.  D  |  A. p  e.  A  A. q  e.  A  (

Distinct variable groups:    q, p, A    D, f    f, p, q, K    f, W, p, q
Allowed substitution hints:    A( f)    B( f, q, p)    D( q, p)    T( f, q, p)    H( f, q, p)    .\/ ( f,
q, p)    .<_ ( f, q, p)    ./\ ( f, q, p)

Proof of Theorem ltrnset
Dummy variable  w is distinct from all other variables.
