{wiki=Euler–Fokker_genus}

The Euler–Fokker genus is a concept from the field of topology, specifically dealing with the classification of surfaces. Named after mathematicians Leonhard Euler and Willem Fokker, the genus of a surface is a topological invariant that represents the maximum number of cuttings you can make without dividing the surface into separate pieces; in simpler terms, it counts the number of "holes" in a surface. For example: - A sphere has a genus of 0 (no holes).
