Where, Symmetries, on the other hand, are transformations that leave an object or a system unchanged in some way. These transformations can be represented as elements of a group, and the study of symmetries is closely related to the study of groups. The work of this master’s memo will consist in studying the interplay between groups and symmetries.enSymmetry groupgroup actiondistanceeuclidean groupThesis
