Properties

Appears in sequences

• Primes that contain only the digits (2, 5, 7).at n=28A214705
• Primes p which are floor of Root-mean-cube (RMC) of prime(n), prime(n+1) and prime(n+2).at n=20A239941
• Primes p such that p and prime(p) end with the same three digits.at n=12A271045
• Take a prime, convert it to base 2. Consider it as a string of digits and delete its leftmost and rightmost digit. Leading zeros are kept. Repeat the process. a(n) is the least prime that, in the first n steps of this process, generates a string that is a prime read in base 2.at n=7A296807
• Lesser of cousin happy primes.at n=21A387896
• Prime numbersat n=5848
