%N Number of conjugacy classes in the symmetric group S_n that have even number of elements.
%C The total number of conjugacy classes of S_n is the partition function p(n) (sequence A000041) and the number of conjugacy classes that have odd number of elements is given in A060632 so a(n) = A000041(n)  A060632(n) for n >= 1
%Y A000041, A060632.
