Catalan's minimal surface

In differential geometry, Catalan's minimal surface is a minimal surface originally studied by Eugène Charles Catalan in 1855.[1]

Catalan's minimal surface.

It has the special property of being the minimal surface that contains a cycloid as a geodesic. It is also swept out by a family of parabolae.[2]

The surface has the mathematical characteristics exemplified by the following parametric equation:[3]
