Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N a(n) = the n-th divisor of the smallest positive integer with exactly n^2 divisors.

%e The smallest positive integer with 5^2 divisors = A061707(5) = 1296. The first 5 of the 25 divisors of 1296 are: 1,2,3,4,6. Since the 5th divisor is 6, then a(5) = 6.

%Y Cf. A061707.
