GROUP THEORY SYMBOL
GTSGClasses[space group, basis]
gives the classes of a factor group of the factor group G/T (G being a space group, T the group of pure lattice translations)."
- An element of a group is said to be conjugate to another element , if there exists an element such that . A set of mutually conjugate elements of is called "class" or "conjugacy class" of a group .
