Theorem 4noncolr2

Description: A way to express 4 non-colinear atoms (rotated right 2 places). (Contributed by NM, 11-Jul-2012)

Ref Expression
Hypotheses 3noncol.l = ( le ‘ 𝐾 )
3noncol.j = ( join ‘ 𝐾 )
3noncol.a 𝐴 = ( Atoms ‘ 𝐾 )
Assertion 4noncolr2 ( ( ( 𝐾 ∈ HL ∧ 𝑃𝐴𝑄𝐴 ) ∧ ( 𝑅𝐴𝑆𝐴 ) ∧ ( 𝑃𝑄 ∧ ¬ 𝑅 ( 𝑃 𝑄 ) ∧ ¬ 𝑆 ( ( 𝑃 𝑄 ) 𝑅 ) ) ) → ( 𝑅𝑆 ∧ ¬ 𝑃 ( 𝑅 𝑆 ) ∧ ¬ 𝑄 ( ( 𝑅 𝑆 ) 𝑃 ) ) )
