Hypotheses
Ref Expression
isline4.b 𝐵 = (Base‘𝐾)
isline4.c 𝐶 = ( ⋖ ‘𝐾)
isline4.a 𝐴 = (Atoms‘𝐾)
isline4.n 𝑁 = (Lines‘𝐾)
isline4.m 𝑀 = (pmap‘𝐾)
Assertion
Ref Expression
isline4N ((𝐾 ∈ HL ∧ 𝑋𝐵) → ((𝑀𝑋) ∈ 𝑁 ↔ ∃𝑝𝐴 𝑝𝐶𝑋))
Distinct variable groups:   𝐴,𝑝   𝐵,𝑝   𝐾,𝑝   𝑀,𝑝   𝑋,𝑝
Allowed substitution hints:   𝐶(𝑝)   𝑁(𝑝)

Proof of Theorem isline4N
Dummy variable 𝑞 is distinct from all other variables.
