Abstract
How must 2N non-overlapping equal circles forming antipodal pairs be packed on a sphere so that the angular diameter of the circles will be as great as possible? In this note, some unnoticed putative solutions to this problem are mentioned, and attention is called to the Danzerian rigidity of the graphs of locally optimal antipodal packings.
