Hoffman's Minimal Surface
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).
