• Expansion of 1/(1 - 2*x - 2*x^2 - x^3).at n=11A077936
• Maximal term of TRIP-Stern sequence of level n corresponding to permutation triple (e,13,132).at n=31A271487
• Solution of the complementary equation a(n) = a(n-1) + a(n-2) + n*b(n-1), where a(0) = 2, a(1) = 4, b(0) = 1, b(1) = 3, and (a(n)) and (b(n)) are increasing complementary sequences.at n=17A296292
• Let f(n) be equal to n + S(n) + S(S(n)) ... + S(S(S..(n))), where the last term is less than 10 and S(n) is the sum of digits. This is the sequence of numbers k such that the equation f(x) = k has a record number of solutions.at n=5A309393
• Sum of the prime numbers in, but not on the border of, an n X n square array whose elements are the numbers from 1..n^2, listed in increasing order by rows.at n=31A344847
