WebFeb 9, 2024 · It’s now easy to see that in Property 5, the Gram determinant is 0 if the xi x i ’s are linearly dependent, and attains its maximum if the xi x i ’s are pairwise orthogonal (a quick proof: in the above matrix, rij = 0 r i j = 0 if i≠j i ≠ j ), which corresponds exactly to the square of the volume of the hyperparallelepiped spanned by the xi x i ’s.
