Additional generators of Euclidean normalizer:
  Number of structure-seminvariant vectors and moduli: 1
    Vector    Modulus
    (0, 0, 1) 0
  Inversion through a centre at: 0,0,0

Grid factors implied by symmetries:
  Space group: (3, 3, 6)
  Structure-seminvariant vectors and moduli: (1, 1, 1)
  Euclidean normalizer: (3, 3, 6)

  All points of a grid over the unit cell are mapped
  exactly onto other grid points only if the factors
  shown above are factors of the grid.
