• Number of 2 X n 0..2 arrays with antidiagonals unimodal and rows and diagonals nondecreasing.at n=23A224000
• Lengths of prefixes of the infinite string of digits repeat(1379) that are prime.at n=14A247025
• Triangle read by rows: T(m,n) is the label of the largest square that an (m,n)-leaper (a generalization of a chess knight) reaches before 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=39A306197
