%N Self-describing sequence: a(n) gives the number of primes in the sequence which are strictly < [a(n)]^2.
%e There are 0 primes < 0^2 (=0) in the whole sequence;
%e There are 2 primes < 2^2 (=4) -- they are "2" and "3");
%e There are 3 primes < 3^2 (=9) -- they are 2, 3 and 5;
%e There are 4 primes < 4^2 (=16) -- they are 2,3,5 and 7;
%e etc.
