Using the well-known lattice which was constructed by Korkin-Zolotarev (containing 240 minimal vectors) and applying an approach based on the positive definite functions on the Gegenbauer system, in this paper it is shown that the minimum of the potential energy of interactions of 240 unit charges placed on the sphere in \(\mathbb{R}^8\) is attained on the minimal vectors and it is equal to \({{637975} \over {72}}\).
