%N Number of integer squares <= n^3.

%C a(n) = number of terms in n-th row of A167222. [From _Reinhard Zumkeller_, Oct 31 2009]

%F a(n) = floor(n^(3/2))+1 = A000093(n) + 1.

%e Squares <= 3^3=27: 0, 1, 4, 9, 16 and 25, hence a(3)=6;

%Y Cf. A065733, A077113.

%Y Cf. A167223. [From _Reinhard Zumkeller_, Oct 31 2009]
