- Let A(n) = #{(i,j): i^2 + j^2 <= n}, V(n) = Pi*n, P(n) = A(n) - V(n); A000099 gives values of n where |P(n)| sets a new record; sequence gives A(A000099(n)).at n=34A000323
- Numbers whose base-5 representation contains exactly three 0's and three 4's.at n=28A045217
- Numbers n for which there are exactly seven k such that n = k + (product of nonzero digits of k).at n=5A096928
- Numbers of the form (7^j + 9^k)/2, for j and k >= 0.at n=34A226795
