• Numbers k such that 2*k^2 + 17 is a square.at n=13A144797
• a(0)=-2, a(1)=3; thereafter a(n) = 2*a(n-1) + a(n-2).at n=14A221172
• Triangle read by rows: T(n,k) = t(n-k, k); t(n,m) = f(m)*t(n-1,m) + f(n)*t(n,m-1), where f(x) = 6*x + 2.at n=17A257616
• Triangle read by rows: T(n,k) = t(n-k, k); t(n,m) = f(m)*t(n-1,m) + f(n)*t(n,m-1), where f(x) = 6*x + 2.at n=18A257616
