Musin's conjectures: a(5) = 32, a(24) = 144855. %C A127081 "Let H be a closed half-space of n-dimensional Euclidean space. Suppose S is a unit sphere in H that touches the supporting hyperplane of H. The one-sided kissing number B(n) is the maximal number of unit nonoverlapping spheres in H that can touch S." [Musin] %H A127081 Oleg R.
