I need to calculate rank of the some
 elliptic Curves,(espicially getting generators or finding a rational point
 on the elliptic curves) but I can not do this by my computer due to limitte
 capacity ; please if possible, calculate rank of  these elliptic curves.

 The elliptic curve is
 Y^2=X^3 - (3h^2)X^2 + 3h(h^3-h)X -(h^3-h)^2.

 for h=967, 1198, 1787, 1987,

  h=2459, 2572, 2711, 2797, 2971, 4999


 please if possible find a generator for some of these elliptic curves.
