Description: Lemma for cvmlift 33261. Putting the results of cvmliftlem11 33257, cvmliftlem13 33258 and cvmliftmo 33246 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.
