• Expansion of (1+x)/(1-2x-x^2-x^3).at n=12A116413
• Number of distinct finite languages over binary alphabet, whose minimum regular expression has reverse Polish length 2n-1.at n=7A211942
• Maximal term of TRIP-Stern sequence of level n corresponding to permutation triple (e,132,e).at n=35A271489
• The sum of the numbers on straight lines of incrementing length n when drawn over numbers of the square spiral, where each line contains numbers which sum to the minimum possible value, and each number on the spiral can only be in one line. If two or more lines exist with the same sum the one containing the smallest number is chosen.at n=46A340974
