A B . C Figure 1: Three different positions for atomic centres in a stacking sequence of hexagonally close-packed layers. Figure 1 shows three possible positions for centres of atoms in a stacking sequence of hexago- nally close-packed layers. Consider the following two stacking sequences: (i) ABC ABC ABC ABC... (ii) ABBAABBAABBA.... For each case, state whether it is close-packed in three dimensions. If it is close-packed, then give the conventional name associated with this structure.
