COMMENT
|
The total number of irreducible representations of S_n is the partition function partition(n) (sequence A000041) and the number of irreducible representations of the symmetric group S_n with their degree not divisible by 3 is given in A060840 so a(n) = A000041(n) - A060840(n).
|
|
EXAMPLE
|
a(3) = 0 because the degrees of the irreducible representations of S_3 are 1,1,2.
