Agree with Raul's statement above. This is a great discovery made by Ramanujan. A cube can be found by the sum of three cubes where one of the cubes is always the cube of 1!! Amazing!!! I think it may be that this can be extended to further developments including a cube being the sum of four cubes or more with perhaps a constant cube in place, perhaps other than cube of 1...
