WebJul 5, 2024 · The most symmetry a triclinic crystal can have is an inversion center ( 1 ). In some references, the hexagonal and rhombohedral systems are considered divisions within a larger system instead of being separate. We are not doing that in this book because doing so adds complication and is not useful.
