Theorem cdlemf 34869
 Description: Lemma F in [Crawley] p. 116. If u is an atom under w, there exists a translation whose trace is u. (Contributed by NM, 12-Apr-2013.)
Hypotheses
Ref Expression
cdlemf.l = (le‘𝐾)
cdlemf.a 𝐴 = (Atoms‘𝐾)

cdlemf.r 𝑅 = ((trL‘𝐾)‘𝑊)
Assertion
Ref Expression
cdlemf (((𝐾 ∈ HL ∧ 𝑊𝐻) ∧ (𝑈𝐴𝑈 𝑊)) → ∃𝑓𝑇 (𝑅𝑓) = 𝑈)
Distinct variable groups:   𝐴,𝑓   𝑓,𝐻   𝑓,𝐾   ,𝑓   𝑇,𝑓   𝑈,𝑓   𝑓,𝑊
Allowed substitution hint:   𝑅(𝑓)

Proof of Theorem cdlemf
Dummy variables 𝑝 𝑞 are mutually distinct and distinct from all other variables.
