A minimal embedded surface discovered
in 1992 consisting of a helicoid with a Hole and Handle
(*Science News* 1992).
It has the same topology as a punctured sphere with a handle, and is only the
second complete embedded minimal surface of finite topology and infinite total curvature
discovered (the Helicoid being the first).

A three-ended minimal surface of Genus 1 is sometimes also called Hoffman's minimal surface (Peterson 1988).
