 Nov3 awarded Yearling May14 comment Eigenvalues of $\sum_{i=1}^n \frac{(x_i - x_{i-1})^2}{\lambda_i}$ Thanks. I knew that the determinant is $\prod_{i=1}^n\lambda_i^{-1}$ and I was guessing if that was the case for the eigenvalues.

To decipher with Vigenère substitution one should look for patterns in the text, same idea but little more complicated.
