GENUS: A topologically invariant property of a surface defined as:
the largest number of nonintersecting simple closed curves that can be drawn on the surface without separating it.
Roughly speaking, it is the number of holes in a surface.
The genus g of a surface, also called the geometric genus, is related to the Euler characteristic $chi$ by $chi==2-2g$.
The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along closed
simple curves without rendering the resultant manifold disconnected. It is equal to the number of handles on it.
