%N Total sum of the numbers of partitions with positive k-th ranks of all partitions of n.

%C For the definition of k-th rank see A208478.

%e For n = 4 the partitions of 4 and the four types of ranks of the partitions of 4 are

%e The number of partitions of 4 with positive k-th ranks are 2, 1, 2, 1 so the total sum is a(4) = 2+1+2+1 = 6.
