The kissing number is used to solve problems involving the close-packing of these figures.
The kissing number is used to solve problems involving the close-packing of these figures. Repeatedly slicing and linking tori creates the Alexander horned type of this figure. The Banach-Tarski paradox involves disassembling one of these figures in order to form two. The coordinate system on these figures has a volume element equal to rho squared sin theta d-rho d-theta d-phi, and triangles drawn on the surface of them have angles that sum to greater than (*) 180 degrees. Each point on these figures has an infinite number of great circles running through it. The volume of one of these figures is equal to four-thirds pi r cubed. For 10 points, name these three-dimensional figures which consist of all of the points equidistant from a center.
