Hi all
What symmetries are there usually in a lattice? Let us say for example that I look at a lattice having the form (each "x" is an atom)
x x x x x x x x x
x x x x x x x x x
x x x x x x x x x
x x x x x x x x x
x x x x x x x x x
Of course there is translational symmetry (assuming homogeneous system). But what other symmetries are usually responsible for degeneracies?
