This article gives the statement and possibly, proof, of an implication relation between two commutative unital ring properties. That is, it states that every commutative unital ring satisfying the first commutative unital ring property must also satisfy the second commutative unital ring property

Statement

Symbolic statement

Let be a Noetherian and . Let be a minimal prime ideal among those containing . Then, the codimension of is at most 1.

Property-theoretic statement

The property of commutative unital rings of being a Noetherian ring is stronger than the property of being a ring satisfying PIT.
