GTRegularRepresentation[group]
gives the regular representation of a group.

DetailsDetails

  • Consider a finite group with elements ,..., . The matrix elements of the -dimensional representation matrix are given by
  • .
  • For the character of each representation matrix it holds,
  • .
  • Let be a group with irreducible representations ,...,. Each irreducible representation occurs times within the regular representation , where is the dimension of the irreducible representation .
