• 5 consecutive primes differ by 2n or more starting at a(n).at n=8A054699
• Lesser of two consecutive primes such that n*p + q is a perfect square, p < q.at n=19A064545
• Primes p=prime(i) of level (1,4), i.e., such that A118534(i) = prime(i-4).at n=24A216177
• Let N(p,i) denote the result of applying "nextprime" i times to p; a(n) = smallest prime p such that N(p,3) - p = 2*n, or -1 if no such prime exists.at n=39A339943
• Let N(p,i) denote the result of applying "nextprime" i times to p; a(n) = smallest prime p such that N(p,4) - p = 2*n, or -1 if no such prime exists.at n=50A339944
• a(n) is the least prime p such that, if q is the next prime after p and d = q-p, then p-n*d, p+n*d, q-n*d and q+n*d are all prime.at n=46A353697
• Primes such that the next 10 prime gaps are all distinct.at n=15A372550
