This TLP has covered the following topics:

The mathematical description of the atomic structure of a crystal.
The different lattice types.
What a lattice vector, unit cell & motif are and how they are relevant to describing crystals.
Close packing and the packing efficiency of a crystal structure.
What symmetry operators are present within a crystallographic lattice and how only specific combinations of such symmetry elements may exist.
Bravais lattice and Point Groups.
How to construct the plan view of a 2×2 unit cell.
