• prime(k) for those k where floor((2*(prime(k+1)-prime(k))*PrimePi(k) mod (8*k))/k) = m with m = 13.at n=21A109567
• Primes p such that q-p = 58, where q is the next prime after p.at n=6A204668
• a(n) is the smallest prime p such that, for m >= nextprime(p), there are more composites than primes in the range [2, m], where multiples of primes prime(1) through prime(n) are excluded.at n=7A361915
