Description: Lemma for cvmlift 33161. Putting the results of cvmliftlem11 33157, cvmliftlem13 33158 and cvmliftmo 33146 together, we have that 𝐾 is a continuous function, satisfies 𝐹 ∘ 𝐾 = 𝐺 and 𝐾(0) = 𝑃, and is equal to any other function which also has these properties, so it follows that 𝐾 is the unique lift of 𝐺.
