... axis , but we should not expect the lattice to have a five - fold rotation axis . In Fig . 9a we show what happens if we try to construct a periodic lattice having five- fold symmetry : the pentagons do not fit together neatly . We see ...

... axis 2 , a rotation of π takes one dot into the other . With a two - fold axis and one mirror plane there is automatically a second mirror plane normal to the first , and we have the point group 2mm with four equivalent points . not ...

... axis , the plane may be specified by giving the positions of the points along the axes in terms of the lattice constants . If , for example , the atoms determining the plane have coordinates ( 4 , 0 , 0 ) , ( 0 , 1 , 0 ) , ( 0 , 0 , 2 ) ...
