%N Numbers n such that n-th partition number A000041(n) is a 3-almost prime (A014612).
%C 3-almost prime analog of: A046063 Numbers n such that n-th partition number A000041(n) is prime; A065729 n-th partition number (A000041[n]) is a semiprime. See also A065728 Partition numbers (A000041) that are semiprimes (A001358).
%F A000041(a(n)) in A014612.
%e a(1) = 9 because P(9) = 30 = 2 * 3 * 5.
%e a(2) = 10 because P(10) = 42 = 2 * 3 * 7.
%e a(3) = 16 because P(16) = 231 = 3 * 7 * 11.
