- Using Euler's 6-term sequence A014556, we define the partial recurrence relation a(0)=2, a(1)=3, a(2)=5; a(k) = 2*a(k-1) - 1 - (-2)^(k-2), 3 <= k <= 5.at n=19A082605
- a(0) = 6; for n>0, a(n) = 2*a(n-1) - 1.at n=17A083575
- a(n) = 10*4^n+1.at n=8A199209
- Clique covering number of the n-Sierpinski tetrahedron graph.at n=10A307702
- a(n) = 5*2^n - (-1)^n.at n=17A321643
- Number of subsets of {1..n} whose elements have the same number of distinct prime factors.at n=38A339512
