• Numbers k such that the period of the continued fraction for sqrt(k) contains exactly 53 ones.at n=1A031821
• Bessel function Y_0(n) is a monotonically decreasing positive sequence.at n=34A046961
• Number of 6-bead necklaces where each bead is an unlabeled rooted tree, by total number of nodes.at n=11A058855
• Numbers n such that A002496(n) mod A002496(n-1) is a perfect square.at n=41A247592
• Triangle read by rows: T(m,n) is the label of the ending square of an (m,n)-leaper (a generalization of a chess knight) when it can no longer move, starting on a board with squares spirally numbered, starting at 1; 1 <= n < m. Each move is to the lowest-numbered unvisited square.at n=13A323750
