Amiram Eldar, Table of n, a(n) for n = 1..10000

Formula

a(n) = A007956(A048753(n))/A032741(A048753(n)). - Amiram Eldar, Sep 06 2019

Example

a(6)=21, n=21; quotient of product of aliquot divisors divided by number of aliquot divisors is 7 (aliquot divisors of 21 = 1*3*7 and 21/3 divisors = 7). Since 7 is integral, add to sequence.
