Theorem lvolex3N 39532

Description: There is an atom outside of a lattice plane i.e. a 3-dimensional lattice volume exists. (Contributed by NM, 28-Jul-2012.) (New usage is discouraged.)

Hypotheses

Ref	Expression
lvolex3.l	⊢ ≤ = (le‘𝐾)
lvolex3.a	⊢ 𝐴 = (Atoms‘𝐾)
lvolex3.p	⊢ 𝑃 = (LPlanes‘𝐾)

Assertion

Ref	Expression
lvolex3N	⊢ ((𝐾 ∈ HL ∧ 𝑋 ∈ 𝑃) → ∃𝑞 ∈ 𝐴 ¬ 𝑞 ≤ 𝑋)

Distinct variable groups:   𝐴,𝑞   𝐾,𝑞   ≤ ,𝑞   𝑋,𝑞

Allowed substitution hint:   𝑃(𝑞)

Proof of Theorem lvolex3N

Dummy variables 𝑟 𝑠 𝑡 are mutually distinct and distinct from all other variables.
