- The image displays a single, continuous line forming a shape that resembles the letter 'C'.
- This shape is closed, meaning the line starts and ends at the same point, creating an enclosed area.
- It has one hole in the middle, which is characteristic of the letter 'C' when drawn as a closed loop.
- The shape is topologically equivalent to a circle with a single hole, which is known as a torus with one hole or a genus-1 surface.
- In topology, the number of holes in a surface is called its genus. A sphere has genus 0, a torus (donut) has genus 1, and so on.
- Therefore, the shape in the image has a genus of 1.
