%N One-sided kissing number for spheres in n-dimensional Euclidean space.
%C a(8) = 183. Musin's conjectures: a(5) = 32, a(24) = 144855.
%C "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]
