Theorem cvmliftlem5 36140

Description: Lemma for cvmlift 36150. Definition of 𝑄 at a successor. This is a function defined on 𝑊 as ^◡(𝑇 ↾ 𝐼) ∘ 𝐺 where 𝐼 is the unique covering set of 2^nd ‘(𝑇‘𝑀) that contains 𝑄(𝑀 − 1) evaluated at the last defined point, namely (𝑀 − 1) / 𝑁 (note that for 𝑀 = 1 this is using the seed value 𝑄(0)(0) = 𝑃).
