This is an unsorted list of, in a sense, the sporadic solutions, which exclude infinite subsequences corresponding to the n points of the n-gon on the 2-sphere (circle), the n+1 points of the simplex on the n-sphere, the 2n points of the cross polytope on the n-sphere and the (q+1)*(1+q^3) points on isotropic subspaces of the q*(1+q^3)/(q+1)-sphere where q is a prime power. %H A153054 B.

Schurmann, <a href="https://arxiv.org/abs/math/0611451">Experimental study of energy-minimizing point configurations on spheres</a>, arXiv:math/0611451 [math.MG], 2006-2008. %e A153054 120 is in the sequence because of the 120 points which are vertices of the regular 600-cell in dimension 4. %e A153054 196560 is in the sequence because of the Leech lattice minimal vectors in 24 dimensions. %Y A153054 Cf.
