The term mesh is commonly used with two meanings:
- In a two-dimensional pattern possessing rotational symmetry, the rotation points constitute the nodes of a net and divide the plane into regions that are called meshes. The number of meshes meeting at any rotation point equals twice the order of the rotation at that point.
- A two-dimensional unit cell is also sometimes called a mesh.
According to Loeb (1971), only the first use would be correct.
