• Larger member of twin prime pairs whose sum is a square.at n=21A118593
• Greatest prime factor of 2*n^4 + 1.at n=20A140538
• Primes prime(k) such that 2*(prime(k)^2 - prime(k-1)^2) is a fourth power.at n=3A332615
• Odd integers k such that 5^((k-1)/2) + 1 == 0 (mod k*(k-1)/2).at n=25A337829
• a(n) is the smallest prime p such that the number of distinct values of the ratio (number of nonnegative m < p such that m^k == m (mod p))/(number of nonnegative m < p such that -m^k == m (mod p)) is equal to n for some nonnegative k.at n=25A340281
