A square wheel is a wheel that, instead of being circular, has the shape of a square. Such a wheel can roll smoothly if the ground consists of evenly shaped inverted catenaries of the right size and curvature. Stan Wagon, a mathematician at Macalester College, has constructed a bicycle with square wheels, together with a special track for riding it on.
For other improbable wheels, see Reuleaux polygon.
