• If m = p_i^e_i, n=Product p_j^f_j, set G_m(n) = Product p_{j+i}^{f_j*e_i}; extend G_m to all m by multiplicativity; sequence gives a(n)=G_n(n).at n=34A045974
• a(n) = prime(n-2)*prime(n-1)^2*prime(n).at n=5A066116
• Numerator of J(n) = A000356(n)/A000309(n) (average number of 4-colorings of rank 0 in a rooted nonseparable map which is trivalent and has 2n nodes).at n=8A097872
• Nonsquarefree "year numbers" (numbers n such that phi(n) = 2*phi(sigma(n)): A137815).at n=4A137816
• Numbers n such that n^4 is a sum of 4th powers of four nonzero integers whose sum is n.at n=13A138760
• a(n) is the smallest prime(n)-rough number k that has more divisors than k-1 and more divisors than k+1.at n=5A347719
