This page and the links to it are an interactive self-assessed exercise that all you to test your cognitive skills concerning points made on the previous page. The object is to relate the positions of symmetry equivalent points with lattice translations and/or a symmetry operator belonging to the space group P21/c.

Click on the space group diagram to identify the points that are symmetry equivalent to the one shown in magenta in the bottom left-hand corner of the figure (with fractional coordinates x=0.07, y=0.11, z=0.15). Every item coloured blue is clickable.

If you wish to see the projection of the unit cell viewed down either the a or c axes, then click on either the arrow in the bottom right-hand corner of the diagram or directly on the labels indicating the axes directions.

Check list of figures which have been accessed in this exercise.
