cdlemg1ltrn.l	⊢ ≤ = (le‘𝐾)
cdlemg1ltrn.a	⊢ 𝐴 = (Atoms‘𝐾)
cdlemg1ltrn.h	⊢ 𝐻 = (LHyp‘𝐾)
cdlemg1ltrn.f	⊢ 𝐹 = (℩𝑓 ∈ 𝑇 (𝑓‘𝑃) = 𝑄)
cdlemg1ltrn.t	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)
cdlemg1id.b	⊢ 𝐵 = (Base‘𝐾)

Assertion

Ref	Expression
cdlemg1idN	⊢ (((((𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻) ∧ (𝑃 ∈ 𝐴 ∧ ¬ 𝑃 ≤ 𝑊) ∧ (𝑄 ∈ 𝐴 ∧ ¬ 𝑄 ≤ 𝑊)) ∧ 𝑋 ∈ 𝐵) ∧ 𝑃 = 𝑄) → (𝐹‘𝑋) = 𝑋)
