Properties

Appears in sequences

• Let (p1,p2), (p3,p4) be pairs of twin primes with p1*p2=p3+p4-1; sequence gives values of p2.at n=36A047977
• Numbers n such that absolute value of Sum_{k=1..n} mu(k)/k sets a new minimum.at n=18A070892
• Prime numbers ending in the prime number 101.at n=14A167626
• Primes of the form p=floor(T/6), T are triangular numbers.at n=38A171595
• Primes p such that q = 2*p^3-1 and 2*p*q^2-1 are both prime.at n=16A224614
• Bertrand primes II: a(n) is the largest prime < 2*a(n-1)-2.at n=15A227770
• Primes p such that p+12, (p+1)/2, and (p+13)/2 are also prime.at n=22A283869
• Numbers k such that k*(k+1) divides tribonacci(k) (A000073(k)).at n=12A299156
• Prime numbersat n=5693
