  abstract = {We perform a numerical study of a knotted flow through a cylinder.
	In this example - which is due to Conley - based on certain assumptions
	on the flow Wazewski's Theorem guarantees the existence of an unstable
	invariant set inside the cylinder. We explicitly construct a flow
	with the desired properties and approximate the corresponding invariant
	set using set oriented multilevel subdivision techniques.}
