Nuprl Lemma : RankEx4_size_wf
∀[p:RankEx4()]. (RankEx4_size(p) ∈ ℕ)
Proof
Definitions occuring in Statement :
RankEx4_size: RankEx4_size(p),
RankEx4: RankEx4(),
nat: ℕ,
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
RankEx4_size: RankEx4_size(p),
