Properties

Appears in sequences

• Let Oc(n) = A005900(n) = n-th octahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Oc(i) = Oc(j)+Oc(k), ordered by increasing i; sequence gives j values.at n=7A053677
• Primes whose 10's complement is a triangular number.at n=38A082992
• Primes of the form triangular(p) + 1, where p is a prime.at n=20A231988
• Primes of form n^2 + 20736.at n=21A256840
• Numbers k such that one of k, k+1, k+2 is prime and the other two are semiprimes, and one of R(n), R(n+1), R(n+2) is prime and the other two are semiprimes, where R = A004086.at n=17A354285
