OEIS Sequences

Primes having only {1, 5, 7} as digits. A260828

Smallest of 3 consecutive prime numbers such that p1·p2·p3+d1+d2+1=average of twin prime pairs, d1(δ)=p2-p1,d2(δ)=p3-p2. A153406

Primes p for which there are exactly as many primes in the range [p², p·nextprime(p)] as there are in the range [p·nextprime(p), nextprime(p)²], where nextprime(p) gives the next prime after prime p. A256472

Let p_4,1(m) be the m-th prime == 1 (mod 4). Then a(n) is the smallest p_4,1(m) such that the interval(p_4,1(m)*n, p_4,1(m+1)*n) contains exactly one prime == 1 (mod 4). A210475
