- Expansion of (3 - 21*x + 4*x^2)/((x-1)*(x^2 - 6*x + 1)).at n=6A009759
- a(n) = (a(n-1) * a(n-6) + 2 * a(n-3) * a(n-4)) / a(n-7). a(1) = ... = a(7) = 1. Somos-7 variation.at n=16A064268
- Consider the triangle in which the j-th row begins with prime(j) and is the arithmetic progression with least common difference such that the remaining j-1 terms are composite and not divisible by prime(j). Sequence gives last term in each row.at n=28A095182
