Line L1 passes through the point (1, 2, 3) and is parallel to the z-axis. Line L2 passes through the point (λ, 5, 6) and is parallel to the y-axis. If for λ = λ₁, λ₂ with λ₂ < λ₁ the shortest distance between these two lines is 3, then the square of the distance of the point (λ₁, λ₂, 7) from the line L1 is:
