- Self-conjugate digitized partition numbers.at n=30A068325
- Number of ways the set {1,2,...,n} can be split into three subsets of which the three sums are consecutive.at n=16A113039
- Number of base 28 n-digit numbers with adjacent digits differing by one or less.at n=8A126382
- Number of walks within N^2 (the first quadrant of Z^2) starting at (0,0) and consisting of n steps taken from {(-1, -1), (-1, 0), (0, 1), (1, -1), (1, 0), (1, 1)}.at n=7A151324
- Number of n X 8 binary arrays without the pattern 0 1 diagonally, vertically or antidiagonally.at n=26A188865
- Number of dispersed Dyck paths of length n (i.e., of Motzkin paths of length n with no (1,0)-steps at positive heights) having no base pyramids. A base pyramid is a factor of the form U^j D^j (j>0), starting at the horizontal axis. Here U=(1,1) and D=(1,-1).at n=22A191393
- For k in {2,3,...,9} define a sequence as follows: a(0)=0; for n>=0, a(n+1)=a(n)+1, unless a(n) ends in k, in which case a(n+1) is obtained by replacing the last digit of a(n) with the digit(s) of k^2. This is k(7).at n=40A237344
