Theorem lspindp2 19629

Description: Alternate way to say 3 vectors are mutually independent (rotate right). (Contributed by NM, 12-Apr-2015.)

**Hypotheses**
Ref	Expression
lspindp1.v	⊢ 𝑉 = (Base‘𝑊)
lspindp1.o	⊢ 0 = (0_g‘𝑊)
lspindp1.n	⊢ 𝑁 = (LSpan‘𝑊)
lspindp1.w	⊢ (𝜑 → 𝑊 ∈ LVec)
lspindp2.x	⊢ (𝜑 → 𝑋 ∈ 𝑉)
lspindp2.y	⊢ (𝜑 → 𝑌 ∈ (𝑉 ∖ { 0 }))
lspindp2.z	⊢ (𝜑 → 𝑍 ∈ 𝑉)
lspindp2.q	⊢ (𝜑 → (𝑁‘{𝑋}) ≠ (𝑁‘{𝑌}))
lspindp2.e	⊢ (𝜑 → ¬ 𝑍 ∈ (𝑁‘{𝑋, 𝑌}))

**Assertion**
Ref	Expression
lspindp2	⊢ (𝜑 → ((𝑁‘{𝑍}) ≠ (𝑁‘{𝑋}) ∧ ¬ 𝑌 ∈ (𝑁‘{𝑍, 𝑋})))
