∀ {R : Type u_1} {M : Type u_2} [inst : DivisionRing R] [inst_1 : LinearOrder R] [inst_2 : IsOrderedRing R]
  [inst_3 : AddCommGroup M] [inst_4 : Module R M] {C F : PointedCone R M}, F.IsFaceOf C → F.lineal = C.lineal

The lineality space of a face of a cone agrees with the lineality space of the cone.
