- Consider all integer triples (i,j,k), j >= k > 0, with i^3 = binomial(j+2,3) + binomial(k+2,3), ordered by increasing i; sequence gives i values.at n=25A054208
- Partial sums of cupolar numbers (1/3)*(n+1)*(5*n^2+7*n+3) (A096000).at n=23A117066
- If p and q are twin primes then pq + 1 is always divisible by 3, except for (p,q)=(3,5). Sequence gives values of (pq + 1)/3.at n=28A165280
