Theorem grpods 42195

Description: Relate sums of elements of orders and roots of unity. (Contributed by metakunt, 14-Jul-2025.)

**Hypotheses**
Ref	Expression
grpods.1	⊢ 𝐵 = (Base‘𝐺)
grpods.2	⊢ ↑ = (._g‘𝐺)
grpods.3	⊢ (𝜑 → 𝐺 ∈ Grp)
grpods.4	⊢ (𝜑 → 𝐵 ∈ Fin)
grpods.5	⊢ (𝜑 → 𝑁 ∈ ℕ)

**Assertion**
Ref	Expression
grpods	⊢ (𝜑 → Σ𝑘 ∈ {𝑚 ∈ (1...𝑁) ∣ 𝑚 ∥ 𝑁} (♯‘{𝑥 ∈ 𝐵 ∣ ((od‘𝐺)‘𝑥) = 𝑘}) = (♯‘{𝑥 ∈ 𝐵 ∣ (𝑁 ↑ 𝑥) = (0_g‘𝐺)}))

Distinct variable groups: 𝑥, ↑ 𝐵,𝑘,𝑥 𝑘,𝐺,𝑚 𝑥,𝐺 𝑘,𝑁,𝑚 𝑥,𝑁 𝜑,𝑘 Allowed substitution hints: 𝜑(𝑥,𝑚) 𝐵(𝑚) ↑ (𝑘,𝑚)

Proof of Theorem grpods Dummy variables 𝑑 𝑙 𝑦 𝑖 𝑤 𝑐 are mutually distinct and distinct from all other variables.
