We will now consider three irreducible representations for the permutation group P(3): E A B I : (1) (1) (1) (-1) (1) (-1) C) () I2 : EG sh. (2.70) (2.5) F In : (1) (-1) (1) (1) (1) (1) 2.2. Consider the example of the group P(3) which has six elements. Using the irreducible representations of Sect. 2.3, find the sum of l?. Does the equality or inequality in (2.70) hold? Can P(3) have an irreducible representation with l; = 3? Group P(4) has 24 elements and 5 irreducible representations. Using (2.70) as an equality, what are the dimensionalities of these 5 irreducible representations (see Problem 1.4)?
