Hypotheses lhp2at0nle.l ⊢ ≤ = ( le ‘ 𝐾 )
lhp2at0nle.j ⊢ ∨ = ( join ‘ 𝐾 )

lhp2at0nle.a ⊢ 𝐴 = ( Atoms ‘ 𝐾 )
lhp2at0nle.h ⊢ 𝐻 = ( LHyp ‘ 𝐾 )
Assertion lhp2at0ne ( ( ( ( 𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻 ) ∧ ( 𝑃 ∈ 𝐴 ∧ ¬ 𝑃 ≤ 𝑊 ) ∧ 𝑄 ∈ 𝐴 ) ∧ ( ( ( 𝑈 ∈ 𝐴 ∨ 𝑈 = 0 ) ∧ 𝑈 ≤ 𝑊 ) ∧ ( 𝑉 ∈ 𝐴 ∧ 𝑉 ≤ 𝑊 ) ) ∧ 𝑈 ≠ 𝑉 ) → ( 𝑃 ∨ 𝑈 ) ≠ ( 𝑄 ∨ 𝑉 ) )
