## Main Question or Discussion Point

Hi guys

Ok, so one way to define a Bravais lattice is to say that each lattice point can be reached by

But does that also mean that a lattice with a basis does

Ok, so one way to define a Bravais lattice is to say that each lattice point can be reached by

**R**= l**a**_{1}+m**a**_{2}+n**a**_{3}for some integer m, l and n. Obviously, this cannot be the case when we have a lattice with a basis.But does that also mean that a lattice with a basis does

**not**have primitive vectors?
