The kissing number of ℝn is the maximum number of pairwise-nonoverlapping unit spheres that can simultaneously touch a central unit sphere. Mittelmann and Vallentin (2010), based on the semidefinite programming bound of Bachoc and Vallentin (2008), computed the best known upper bounds for the kissing number for several values of n ≤ 23. In this paper, we exploit the symmetry present in the semidefinite programming bound to provide improved upper bounds for n = 9, …, 23.
