%N Numbers that have more prime digits than nonprime digits.
%C Begins to differ from A046034 at the 21st term (which is the first 3-digit term).

%e 133 is in the sequence as the prime digits are 3 and 3 (those are two digits; counted with multiplicity) and one nonprime digit 1 and so there are more prime digits than nonprime digits. - _David A. Corneth_, Sep 06 2020
