Properties

Appears in sequences

• Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted the two central terms are both 60.at n=6A031648
• Primes of the form 2^x+x*y+2^y, with x and y integers of any sign.at n=19A162573
• Primes of the form 10n^2 - 7.at n=21A201963
• Odd primes whose base-2 representation has no proper substrings that are base-2 representations of odd primes.at n=21A365518
• Square array read by antidiagonals upwards: T(n,k) (for n>1 and k>0) is the smallest k-digit prime p such that prevprime(p) appears as a substring in p^n; or -1 if no such prime exists.at n=41A383613
