The term 'fm-3m' refers to a specific crystallographic space group that is one of the most symmetrical groups in three-dimensional crystallography. This space group is part of the face-centered cubic (FCC) lattice system and features a high degree of symmetry, making it an important reference for the study of crystal structures and symmetry operations. Understanding the symmetry operations associated with fm-3m is crucial as it allows for a clearer analysis of how atoms are arranged in crystalline materials, influencing their physical properties.
congrats on reading the definition of fm-3m. now let's actually learn it.
