Antoine's Necklace
Construct a chain 
of 
components in a solid Torus 
. Now form a chain 
of solid tori in , where
via inclusion. In each component of
, construct a smaller chain of solid tori embedded in that component.Denote the union of these smaller solid tori 
. Continue this process a countable number of times, then theintersection
which is a nonempty compact Subset of
is called Antoine's necklace. Antoine's necklace is Homeomorphicwith the Cantor Set.See also Alexander's Horned Sphere, Necklace
