X be the cuboctahedron (see picture) A subset Y of X's vertices "traps the center" if any small perturbation of the center of X would decrease its distance to at least one point of Y. In order to trap the center, Y must have at least 6 vertices. Can you find all 6-vertex Y's?pic.twitter.com/YPl15uRR3k
