• Numbers having four 4's in base 9.at n=27A043472
• Triangle, T(n, k) = (1/2)*(n+2)! * [x^k]( p(x, n) ), where p(x,0) = 1, p(x,1) = -x, P(x, n) = (1/(n+1))*( (2*n-x)*P(x, n-1) - n*P(x, n-2) ), read by rows.at n=23A136532
• Triangular array read by rows: The sum of squares of the number of common points in all pairs of lattice paths from (0,0) to (x,y), for 0 <= y <= x (the unnormalized second moment).at n=13A306687
• The sum of squares of the number of common points in all pairs of lattice paths from (0,0) to (x,y), for x >= 0, y >= 0 (the unnormalized second moment). The table is read by antidiagonals.at n=31A324010
• The sum of squares of the number of common points in all pairs of lattice paths from (0,0) to (x,y), for x >= 0, y >= 0 (the unnormalized second moment). The table is read by antidiagonals.at n=32A324010
• a(n) is the number of paths of a knight on square a1 to reach a position outside an 8 X 8 chessboard after n steps.at n=6A377018
• Numbers whose binary expansion consists of alternating runs of 1's and 0's where each run of 0's is exactly one shorter than the preceding run of 1's, and the expansion ends with a 0-run.at n=41A387270
