Using ArraySegments might be a readable and short solution (casting your list to array is required):

var list = new List() { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }; //Added 0 in front on purpose in order to enhance simplicity.
int[] array = list.ToArray();
int step = 4;
List listSegments = new List();

for(int i = 0; i < array.Length; i+=step)
{
     int[] segment = new ArraySegment(array, i, step).ToArray();
     listSegments.Add(segment);
}
