Conventional cell

For each lattice, the conventional cell is the cell obeying the following conditions:

  • its basis vectors define a right-handed axial setting;
  • its edges are along symmetry directions of the lattice;
  • it is the smallest cell compatible with the above condition.

Crystals having the same type of conventional cell belong to the same crystal family.
