• Number of Twopins positions.at n=17A005682
• Let Do(n) = A006566(n) = n-th dodecahedral number. Consider all integer triples (i,j,k), j >= k>0, with Do(i) = Do(j) + Do(k), ordered by increasing i; sequence gives i values.at n=11A053017
• Number of ordered pairs of partitions of n with no common parts.at n=19A054440
• Values of n such that n^a-+a are primes, a=11.at n=7A155023
• Half the number of length n integer sequences with sum zero and sum of squares 5618.at n=3A157585
• Triangle read by rows: T(n,k) is the number of Dyck paths of semilength n having k occurrences of the string ududu, where u=(1,1), d=(1,-1).at n=59A246188
• Numbers k such that Bernoulli number B_{k} has denominator 14322.at n=35A295588
