Assertion

Ref	Expression
eldioph4i	⊢ ((𝑁 ∈ ℕ0 ∧ 𝑃 ∈ (mzPoly‘(𝑊 ∪ (1...𝑁)))) → {𝑡 ∈ (ℕ0 ↑𝑚 (1...𝑁)) ∣ ∃𝑤 ∈ (ℕ0 ↑𝑚 𝑊)(𝑃‘(𝑡 ∪ 𝑤)) = 0} ∈ (Dioph‘𝑁))

Distinct variable groups:   𝑡,𝑊,𝑤   𝑡,𝑁,𝑤   𝑡,𝑃,𝑤

Proof of Theorem eldioph4i

Dummy variables 𝑎 𝑏 𝑝 are mutually distinct and distinct from all other variables.
