Nuprl Lemma : I-cube_wf
∀[X:CubicalSet]. ∀[I:Cname List]. (X(I) ∈ Type)
Proof
Definitions occuring in Statement :
I-cube: X(I),
cubical-set: CubicalSet,
coordinate_name: Cname,
list: T List,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
cubical-set: CubicalSet,
I-cube: X(I),
functor-ob: functor-ob(F),
pi1: fst(t)
