Properties

Appears in sequences

• Primes having only {0, 6, 8, 9} as digits.at n=31A053580
• Primes p such that p+2, 2p+1, and 2p+3 are also prime.at n=25A069142
• Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,4,2).at n=14A078948
• Lexicographically earliest sequence of positive integers with the property that a(a(n)) = a(1)+a(2)+...+a(n).at n=30A105753
• Fastest increasing sequence in which a(n) is a prime closest to the sum of all previous terms.at n=16A109278
• Primes of the form k^2 + 13.at n=40A138375
• Primes followed by at least five consecutive primes as closely as possible.at n=27A156114
• Primes that contain all the digits {0,6,8,9} and only these digits.at n=13A156200
• Primes of the form x^2 + 17*y^2, where x and y=x+1 are consecutive natural numbers.at n=12A176622
• Numbers n such that n is a twin prime and 2n + 1 is a twin prime.at n=26A261463
• For a lesser p of twin primes, let B_(p+2) and B_p be sequences defined as A159559, but with initial terms p+2 and p respectively. The sequence lists p for which all differences B_(p+2)(n)-B_p(n)<=6.at n=29A276848
