The D centred cell is the used for the rhombohedral description of the hexagonal lattice. Six right-handed D cell with basis vectors of equal length are obtained from the hP cell by means of one of the following transformation matrices:
D1: 10-1/01-1/111 D2: -101/0-11/111
the other four D cells are obtained by cyclic permutation of the basis vectors.
The resulting hD cell has centring nodes at 1/3,1/3,1/3 and 2/3,2/3,2/3
