Theorem cvlposN

Description: An atomic lattice with the covering property is a poset. (Contributed by NM, 5-Nov-2012) (New usage is discouraged.)

Ref Expression
Assertion cvlposN ⊢ K ∈ CvLat → K ∈ Poset

Proof

Step Hyp Ref Expression
1 cvllat ⊢ K ∈ CvLat → K ∈ Lat
2 latpos ⊢ K ∈ Lat → K ∈ Poset
3 1 2 syl ⊢ K ∈ CvLat → K ∈ Poset
