- Intrinsic 10-palindromes: n is an intrinsic k-palindrome if it is a k-digit palindrome in some base.at n=30A060947
- Triangle read by rows: T(n,k) is the number of deco polyominoes of height n and having k columns ending at an odd level (0<=k<=n). A deco polyomino is a directed column-convex polyomino in which the height, measured along the diagonal, is attained only in the last column.at n=46A121697
- Number T(n,k) of permutations p of [n] such that in 0p the largest up-jump equals k and no down-jump is larger than 2; triangle T(n,k), n>=0, 0<=k<=n, read by rows.at n=62A291680
- Number of permutations p of [n] such that in 0p the largest up-jump equals seven and no down-jump is larger than 2.at n=3A321114
- Numbers k such that k, k+1 and k+2 have the same period of binary representation (A007733).at n=0A333746
