Cox's TheoremLet , ..., be four Planes in General Position through a point and let be a point on the Line . Let denote the Plane . Then the four Planes , , , all pass through one point . Similarly, let , ..., be five Planes inGeneral Position through . Then the five points , , , ,and all lie in one Plane. And so on. See also Clifford's Circle Theorem
