%N Primes that remain prime through 3 iterations of function f(x) = 9x + 10.
%C Primes p such that 9*p+10, 81*p+100 and 729*p+910 are primes. - _Vincenzo Librandi_, Aug 04 2010

%e 11 is in the sequence because it is prime, 9*11 + 10 = 109 is prime, 9*109 + 10 = 991 is prime, and 9*991 + 10 = 8929 is prime. - _Michael B. Porter_, Aug 23 2016
