Properties

Appears in sequences

• Primes that remain prime through 4 iterations of function f(x) = 4x + 3.at n=13A023311
• Schoenheim bound L_1(n,5,4).at n=39A036832
• a(n) = 2*prime(n)^2 - prime(n+1)^2.at n=39A064051
• First occurrence prime gaps of the primes in sequence A002313 (Real primes with corresponding complex primes). a(0) = 2 with length of gap 3. For n>0 the size of the gap in the sequence is 4n, a(n) is the starting prime of the gap.at n=19A084160
• Numbers k such that 13k = 6j^2 + 6j + 1.at n=37A106390

• Numbers k such that 3^k - 32 is prime.at n=17A219049
• Prime numbers p such that p^3 is an interprime = average of two successive primes.at n=37A248799
• L.g.f.: Sum_{n>=1} [ Sum_{k>=1} k^n * x^(2*k-1) ]^n / n.at n=8A276907
• Primes that can be generated by the concatenation in base 3, in ascending order, of two consecutive integers read in base 10.at n=35A287300
• Lesser p of a sexy prime pair such that (p-3)/2 is also the lesser prime of a sexy prime pair.at n=20A358571
