Nuprl Lemma : atom-sdata-not-pair2
∀[a:Atom1]. ∀[d1,d2:SecurityData].  uiff(<d1, d2> = data(a) ∈ SecurityData;False)
Proof
Definitions occuring in Statement : 
sdata-pair: <d1, d2>
, 
atom-sdata: data(a)
, 
sdata: SecurityData
, 
atom: Atom$n
, 
uiff: uiff(P;Q)
, 
uall: ∀[x:A]. B[x]
, 
false: False
, 
equal: s = t ∈ T
Definitions unfolded in proof : 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
uiff: uiff(P;Q)
, 
and: P ∧ Q
, 
uimplies: b supposing a
, 
false: False
, 
prop: ℙ
Latex:
\mforall{}[a:Atom1].  \mforall{}[d1,d2:SecurityData].    uiff(<d1,  d2>  =  data(a);False)
