• n such that A205592(n) > n.at n=25A205594
• Number of n X 3 nonnegative integer arrays with upper left 0 and lower right its king-move distance away minus 3 and every value within 3 of its king move distance from the upper left and every value increasing by 0 or 1 with every step right, diagonally se or down.at n=13A252999
• After the initial 1, numbers k such that A347381 obtains its minimum value at k, of all the divisors d of k larger than one, where A347381 is the distance from n to the nearest common ancestor of n and sigma(n) in the Doudna-tree (A005940).at n=26A374218
• Composite numbers k such that A347381 obtains the same value for all divisors of k that are larger than one, where A347381 is the distance from n to the nearest common ancestor of n and sigma(n) in the Doudna-tree (A005940).at n=8A374219
• a(n) = numerator(b(n)), where b(n) = b(n-1) + n if n is odd and b(n-1)*n/(b(n-1) + n) if n is even, with b(0) = 0.at n=11A392570
