Appears in sequences

• Primes formed by concatenating n with n+1.at n=15A030458
• Primes whose decimal expansion is a concatenation of two or more consecutive increasing numbers (no leading zeros allowed).at n=16A052087
• Largest prime of the form a squarefree number + 1 where the prime divisors of the squarefree number are < n.at n=16A092967
• Largest prime of the form a squarefree number + 1 where the prime divisors of the squarefree number are < n.at n=17A092967
• Primes from merging of 6 successive digits in decimal expansion of the Champernowne Constant.at n=4A104949
• Largest prime of the set of five consecutive primes whose sum of digits is a set of five distinct primes.at n=11A106815
• Consider the array T(n, m) = m-th prime of the form n*i(i+1)/2 +/- 1. This sequence is the main diagonal.at n=33A125765
• Primes formed by concatenating k with k+1, where k+1 is a prime.at n=7A134428
• Primes that are a concatenation of 2*k and 2*k+1 or 2*k and 2*k-1 for some k.at n=27A154530
• Primes formed from the concatenation of n and nextprime(n).at n=23A280376
• a(n) is the largest prime of the form P+1 where P divides prime(n)# and p# denotes the product of all primes <= p.at n=6A365021
• Write down the positive integers. To obtain the terms of the sequence, concatenate groups of these so that the last number of each concatenated group is a prime.at n=26A367431
• List the positive integers but erase commas between terms if the digits just before and just after the comma have opposite parity.at n=47A367595
• Prime numbersat n=9779
