Let ak denote the maximum number with the property that one can place k points on the unit sphere S2 so that the spherical distance between any two different points is at least ak. The exact value of ak is determined only for some small values of k, namely, for k = 12 and k=24. In this paper we give new upper bounds on ak for k=14,15,16,17.
