• The negative number of minimum absolute value not obtainable from 1 in n steps using addition, multiplication, and subtraction.at n=7A229686
• List of quadruples (r,s,t,u): the matrix M = [[4,12,9][2,5,3][1,2,1]] is raised to successive negative powers, then (r,s,t,u) are the square roots of M[1,3], M[1,1], M[3,3], M[3,1] respectively.at n=25A249580
• L.g.f.: log(Product_{k>=1} 1/(1 - x^k/(1 + x))) = Sum_{k>=1} a(k)*x^k/k.at n=14A307675
• Triangle read by rows. T(n, k) = k^n * BellPolynomial(n, -1/k) for k > 0, if k = 0 then T(n, k) = k^n.at n=31A350261
• Triangle read by rows. T(n, k) = B(n, n - k + 1) where B(n, k) = k^n * BellPolynomial(n, -1/k) for k > 0, if k = 0 then B(n, k) = k^n.at n=33A350262
