Nuprl Lemma : rec-combined-class-3-classrel
∀[B,F,X,Y,Z,es,e,v:Top].
(v ∈ rec-combined-class-3(F;X;Y;Z)(e) ~ v ∈ simple-comb-4(F;X;Y;Z;Prior(rec-combined-class-3(F;X;Y;Z)))(e))
Proof

classrel: v ∈ X(e),
uall: ∀[x:A]. B[x],
top: Top,
sqequal: s ~ t

Latex:
\mforall{}[B,F,X,Y,Z,es,e,v:Top].
(v \mmember{} rec-combined-class-3(F;X;Y;Z)(e)
\msim{} v \mmember{} simple-comb-4(F;X;Y;Z;Prior(rec-combined-class-3(F;X;Y;Z)))(e))
