Description: A prime ideal is a proper ideal. (Contributed by Jeff Madsen, 19-Jun-2010.)

**Hypotheses**
Ref	Expression
pridlnr.1	⊢ 𝐺 = (1^st ‘𝑅)
prdilnr.2	⊢ 𝑋 = ran 𝐺

**Assertion**
Ref	Expression
pridlnr	⊢ ((𝑅 ∈ RingOps ∧ 𝑃 ∈ (PrIdl‘𝑅)) → 𝑃 ≠ 𝑋)

Proof of Theorem pridlnr Dummy variables 𝑥 𝑦 𝑎 𝑏 are mutually distinct and distinct from all other variables.
