Description: Lemma for selberg 27526. Estimation of the left-hand side of logsqvma2 27521. (Contributed by Mario Carneiro, 23-May-2016.)

**Assertion**
Ref	Expression
selberglem3	⊢ (𝑥 ∈ ℝ⁺ ↦ ((Σ𝑛 ∈ (1...(⌊‘𝑥))Σ𝑑 ∈ {𝑦 ∈ ℕ ∣ 𝑦 ∥ 𝑛} ((μ‘𝑑) · ((log‘(𝑛 / 𝑑))↑2)) / 𝑥) − (2 · (log‘𝑥)))) ∈ 𝑂(1)

Distinct variable group: 𝑛,𝑑,𝑥,𝑦

Proof of Theorem selberglem3 Dummy variable 𝑚 is distinct from all other variables.
