A set can only have 256 elements, in you case that would have been 4G 
So the max is
   TByteSet = set of Byte;

but usually a set (or enum) is given a reable name like

   TMyEnum = (one, two, three);
   TMySet = set of TMyEnum;

   Numbers: array[0..3] of integer = (1, 2, 3, 4);
   MySet: TMySet = [one, three];

Somehow I get the idea that you mix the definition/use of sets with arrays.
