%N Self-describing sequence: a(n) gives the number of even integers in the sequence which are strictly < [a(n)]^2.
%e There are 3 even integers < 3^2 (=9) in the sequence : they are 4, 6 and 8;
%e there are 4 even integers < 4^2 (=16) -- they are 4,6,8,10;
%e there are 5 even integers < 5^2 (=25) -- they are 4,6,8,10,16;
%e there are 6 even integers < 6^2 (=36) -- they are 4,6,8,10,16,26;
