Discussion Overview
The discussion revolves around the P63/m space group in crystallography, specifically focusing on the meanings of its components as described in the Hermann-Mauguin notation. Participants explore the definitions and implications of the letters and numbers in the space group designation.
Discussion Character
Main Points Raised
- One participant asks about the meaning of the letter "P" and the subscript "3" in the space group P63/m.
- Another participant explains that "P" indicates a primitive group, while "6" signifies a hexagonal space group.
- The subscript "3" is described as indicating a screw axis along the hexagonal c-axis.
- Additionally, "/m" is noted to represent a mirror plane perpendicular to the c-axis.
- It is mentioned that this space group is identified as space group #176.
- A resource, the Bilbao crystallographic server, is suggested for further details on space groups.
Areas of Agreement / Disagreement
