{ [i:Id]. [a:Atom1].  uiff(i:Id||a;True) }

{ Proof }



Definitions occuring in Statement :  Id: Id uiff: uiff(P;Q) uall: [x:A]. B[x] true: True free-from-atom: x:T||a atom: Atom$n
Definitions :  uall: [x:A]. B[x] Id: Id uiff: uiff(P;Q) true: True member: t  T and: P  Q uimplies: b supposing a prop:
Lemmas :  free-from-atom_wf1 true_wf

\mforall{}[i:Id].  \mforall{}[a:Atom1].    uiff(i:Id||a;True)
