• Denominators of continued fraction convergents to sqrt(496).at n=14A041947
• Pell equation solutions (3*a(n))^2 - 10*b(n)^2 = -1 with b(n) = A097315(n), n >= 0.at n=3A097314
• Primes whose base-6 representation also is the base-3 representation of a prime.at n=34A235469
• a(1) = 2. For n>1, let s denote the binary string of a(n-1) with the leftmost 1 and following consecutive 0's removed. Then a(n) is the smallest prime not yet present whose binary representation begins with s.at n=46A262350
