Thanks.

BTW, I want to correct the lemma from:

If n is an odd number then every integral solution (x,y) of the
equation
x^2 + 3y^2 = n^3 is of the form x = u(u^2 - 9v^2), y=3v(u^2 - v^2),
where
gcd(u,v)=1.

into:

If n is an odd number then every integral solution (x,y) of the
equation
x^2 + 3y^2 = n^3 with gcd(x,3y)=1
is of the form x = u(u^2 - 9v^2), y=3v(u^2 - v^2),
where gcd(u,v)=1.
