Theorem ply1lpir 26506

Description: The ring of polynomials over a division ring has the principal ideal property. (Contributed by Stefan O'Rear, 29-Mar-2015.)

**Hypothesis**
Ref	Expression
ply1lpir.p	⊢ 𝑃 = (Poly₁‘𝑅)

**Assertion**
Ref	Expression
ply1lpir	⊢ (𝑅 ∈ DivRing → 𝑃 ∈ LPIR)

Proof of Theorem ply1lpir Dummy variables 𝑖 𝑗 are mutually distinct and distinct from all other variables.
