- Numbers n such that 8*10^n + R_n + 2 is prime, where R_n = 11...1 is the repunit (A002275) of length n.at n=10A103071
- In lunar arithmetic in base 2, the number of divisors of the number 11...1101 (n digits, the binary expansion of 2^n-3).at n=21A188288
- In base-2 lunar arithmetic, out of all odd numbers of length n, it appears that 111..1 (with n ones) has the most lunar divisors; the sequence gives the number of lunar divisors of the runner-up.at n=18A188524
- Irregular triangle read by rows: T(n,k) is the number of binary pattern classes in the (7,n)-rectangular grid with k '1's and (7n-k) '0's: two patterns are in same class if one of them can be obtained by a reflection or 180-degree rotation of the other.at n=31A228166
