Properties

Appears in sequences

• Primes whose 10's complement is a triangular number.at n=29A082992
• Let a,b be prime numbers satisfying the Diophantine equation a^3+b^3=(a+b)*(a^2-a*b+b^2)=c^2. Then the second factor a^2-a*b+b^2 is 3*e^2 for some integer e. This sequence tabulates the 'e' values, sorted by magnitude of c.at n=7A099809
• Primes p such that there exist primes p'<p"<p"'<p""<p such that the concatenation of any two among the {p,...,p""} is prime.at n=27A139005
• A Chebyshev transform of the little Schroeder numbers A001003.at n=9A162548
• Prime numbersat n=7195
