Nuprl Lemma : fl-morph-fl1
∀[J,I:fset(ℕ)]. ∀[f:J ⟶ I]. ∀[x:names(I)]. (((x=1))<f> = dM-to-FL(J;f x) ∈ Point(face_lattice(J)))
Proof
Definitions occuring in Statement :
fl-morph: <f>,
dM-to-FL: dM-to-FL(I;z),
fl1: (x=1),

names: names(I),
lattice-point: Point(l),
fset: fset(T),
nat: ℕ,
uall: ∀[x:A]. B[x],
apply: f a,
equal: s = t ∈ T
