{{no footnotes|date=November 2015}}In mathematical knot theory, a Conway sphere, named after John Horton Conway, is a 2-sphere intersecting a given knot in the 3-sphere or 3-ball transversely in four points. It is essential if it is incompressible and boundary-incompressible in the knot complement.
