Properties

Appears in sequences

• Concatenation of n in base 2 up to base 10 and n in base 10 down to base 2 is prime, all numbers are interpreted as decimals.at n=9A054258
• Primes p such that 2^p-1 and the p-th Fibonacci number have a common factor. Prime terms of A074776.at n=20A080050
• Primes dividing numbers k such that k divides the k-th Lucas number A000032(k).at n=7A129729
• Number of Dyck paths of semilength n such that the minimal number of peaks over all positive levels equals one.at n=11A288540
• Primes p such that A001175(p) = 2*(p+1)/9.at n=34A308786
• Primes in A343812.at n=27A343814
• Irregular table read by rows: T(n,k) is the number of k-gons, k>=3, formed inside a right triangle by the straight line segments mutually connecting all vertices and points on the two shorter edges whose positions on one edge equal the Farey series of order n while on the other they divide its length into n equal segments.at n=56A359977
• Square array read by antidiagonals in ascending order where T(n,k), n>1 and k>=1, is the least prime p, written in base n, starting a run of exactly k consecutive primes with non increasing sum of digits.at n=50A376893
