COMMENTS

The entry N = A104017(n) is written as the product N = p*q*r*... of its k distinct prime factors p<q<r<... . The (k2)nd power multiplied by the decremented p1 of the smallest prime factor and divided by the product of the decremented other prime factors defines a(n): a(n) = (N1)^(k2)*(p1)/( (q1)*(r1)*...).
