Theorem pclemub 12878

Description: Lemma for the prime power pre-function's properties. (Contributed by Mario Carneiro, 23-Feb-2014.) (Revised by Jim Kingdon, 7-Oct-2024.)

**Hypothesis**
Ref	Expression
pclem.1	⊢ 𝐴 = {𝑛 ∈ ℕ₀ ∣ (𝑃↑𝑛) ∥ 𝑁}

**Assertion**
Ref	Expression
pclemub	⊢ ((𝑃 ∈ (ℤ_≥‘2) ∧ (𝑁 ∈ ℤ ∧ 𝑁 ≠ 0)) → ∃𝑥 ∈ ℤ ∀𝑦 ∈ 𝐴 𝑦 ≤ 𝑥)

Distinct variable groups: 𝑛,𝑁,𝑦 𝑥,𝑁,𝑦 𝑃,𝑛,𝑦 𝑥,𝑃 Allowed substitution hints: 𝐴(𝑥,𝑦,𝑛)
