- Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 70.at n=8A031748
- Let Oc(n) = A005900(n) = n-th octahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Oc(i) = Oc(j)+Oc(k), ordered by increasing i; sequence gives k values.at n=8A053678
- Expansion of 1/(1 - x - x^3 - x^5 - x^7).at n=26A117760
- a(n) = 81*n^2 + 9.at n=34A157888
- a(n) = n*(n + 1)*(4*n + 5)/2.at n=36A281381
- a(n) = Sum_{k=1..n} gcd(k, n)^3.at n=43A343497
