For general spin-glass models with non-Gaussian field distributions the corresponding Hessian is a $2^n\\times 2^n$ matrix with the number $n$ of replicas tending to zero eventually. We block-diagonalize this Hessian matrix using representation theory of the permutation group and identify the blocks related to the spin-glass susceptibility.
