COMMENTS
Equals sums of the squares of the terms in rows of triangle A036040;
row sums of A036040 form the Bell numbers (A000110).
EXAMPLE
After the initial a(0)=1, the next few terms are
a(1) = 1^2 = 1,
a(2) = 1^2 + 1^2 = 2,
a(3) = 1^2 + 3^2 + 1^2 = 11,
a(4) = 1^2 + 4^2 + 3^2 + 6^2 + 1^2 = 63,
and continue with sums of the squares of terms in triangle A036040.
