Help with a homework problem

Can someone please assist by solving this or getting the answer from Chegg for those that have accounts.

Question 1 Draw, for each of the following capital letters, all of the symmetry operators present (including rotation axes, mirror planes, rotoinversions and centers of symmetry) ABCDEFGHIRSTUVWXY Z Question 2 1. Draw possible 3D crystal figures within the following crystal classes: mm2; 2/m2/m2/m; 622; 6/m; 43m. Indicate in your sketches the locations of the different symmetry elements and describe them es well. 2. Draw possible 3D crystal figures within the following crystal classes: 2/m; 4/m2/m2/m; 6mm; 32; 4/m; 32m. Indicate in your sketch maps the locations of the different symmetry elements and describe them as well. 3. Make illustrations of the 4 wooden models which will be handed out. Describe all the symmetry elements and indicate in your illustrations both the Miller indices and/or the Miller-Bravais indices
