 OFFSET 1,2 COMMENTS This sequence is the primitive version of A169594. LINKS David A. Corneth, Table of n, a(n) for n = 1..10000 FORMULA a(n) = A169594(A025487(n)). EXAMPLE 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. CROSSREFS Cf. A025487, A169594. a(n) = A309947(n) + 1.
