Theorem cvmliftlem15 30534
 Description: Lemma for cvmlift 30535. Discharge the assumptions of cvmliftlem14 30533. The set of all open subsets 𝑢 of the unit interval such that 𝐺 “ 𝑢 is contained in an even covering of some open set in 𝐽 is a cover of II by the definition of a covering map, so by the Lebesgue number lemma lebnumii 22573, there is a subdivision of the unit interval into 𝑁 equal parts such that each part is entirely contained within one such open set of 𝐽. Then using finite choice ac6sfi 8089 to uniformly select one such subset and one even covering of each subset, we are ready to finish the proof with cvmliftlem14 30533.
