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
.
