Construct a chain
of
components in a solid torus
. Now thicken each component of
slightly to 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
the intersection
which is a nonempty compact subset of is called Antoine's necklace. Antoine's necklace is homeomorphic
with the Cantor set.
