High symmetry directions in a two-dimensional oblique crystal are not well-documented in existing literature, which often focuses on hexagonal or square structures. The discussion seeks clarification on the specific high symmetry points and directions within the Brillouin zone for oblique crystals. Participants express frustration over the lack of resources and examples related to oblique crystals. The need for a visual representation, such as a labeled figure of the Brillouin zone, is emphasized for better understanding. Overall, the conversation highlights a gap in educational materials regarding oblique crystal symmetry.
