17-plane groups

17-plane groups. When the three symmetry elements, mirrors, rotation axis and glide planes are shown on the five nets, 17-plane groups are derived. 17-plane groups. 17-plane groups. 17-plane groups. 17-plane groups. 17-plane groups. 17-plane groups. 17-plane groups. 17-plane groups.

Point Groups (Crystal Classes)

Point Groups (Crystal Classes). Stereographic Projections. Used to display crystal morphology. X for upper hemisphere. O for lower. Stereographic Projections. We will use stereographic projections to plot the perpendicular to a general face and its symmetry equivalents (general form hkl ).
