%N Number of divisors of A025487(n), counting divisor multiplicity in A025487(n).
%C This sequence is the primitive version of A169594.

%F a(n) = A169594(A025487(n)).
%e a(11) = 12 as A025487(11) = 36 and the divisors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 which occur with a multiplicity of 1, 2, 2, 1, 2, 1, 1, 1, 1 respectively (1^m = 1 for all m >= 0). These multiplicities sum to 1 + 1 + 2 + 2 + 1 + 2 + 1 + 1 + 1 + 1 = 12.
%Y Cf. A025487, A169594.
