{ [T:Type]. [g1,g2:LabeledGraph(T)].
    (g1 = g2) supposing (g2  g1 and g1  g2) }

{ Proof }



Definitions occuring in Statement :  lg-contains: g1  g2 labeled-graph: LabeledGraph(T) uimplies: b supposing a uall: [x:A]. B[x] universe: Type equal: s = t
Definitions :  uall: [x:A]. B[x] uimplies: b supposing a lg-contains: g1  g2 exists: x:A. B[x] member: t  T and: P  Q prop: implies: P  Q iff: P  Q rev_implies: P  Q squash: T true: True nat:

\mforall{}[T:Type].  \mforall{}[g1,g2:LabeledGraph(T)].    (g1  =  g2)  supposing  (g2  \msubseteq{}  g1  and  g1  \msubseteq{}  g2)
