All other particles belong to the trivial representation (1) of color SU(3).
The trivial representation (the only finite-dimensional representation in this list).
The symmetric group has two 1-dimensional representations: the trivial representation and the sign representation.
The alternating groups for n 5 have only one one-dimensional irreducible representation, the trivial representation.
The trivial representation of dimension 1.
For the former case, the trivial representation could either lie in the symmetric product, or the antisymmetric product.
Although the trivial representation is constructed in such a way as to make its properties seem tautologous, it is a fundamental object of the theory.
The trivial representation of G is weakly contained in the left regular representation.
The only finite dimensional unitary solution is the trivial representation called the vacuum.
Some authors exclude the trivial representation.
