%N Primes not containing the digit '5'.
%C Subsequence of primes of A052413. - _Michel Marcus_, Feb 22 2015
%C Maynard proves that this sequence is infinite and in particular contains the expected number of elements up to x, on the order of x^(log 9/log 10)/log x. - _Charles R Greathouse IV_, Apr 08 2016

%e From _M. F. Hasler_, Jan 14 2020: (Start)
%e After a(85) = 499, the next prime without digit 5 is a(86) = 601.
%e After a(3734) = 49999, the next term is a(3735) = 60013.
%e After a(27273) = 499979, the next term is 600011.
%e After a(206276) = 4999999, the next term is 6000011. (End)
