How many crystal system are there
The defining property of a crystal is its inherent symmetry. Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis.

A single m shows that the basis has a mirror plane symmetry. (In two dimensions – it is mirror axis). E.g., 3m means that there are 3 equivalent sites within the unit cell and there is one mirror plane. In two dimensions there are 10 point groups.
