If the lateral side lies at the outmost edge of the array, the grooves are of different direction, while at lateral sides forming a line of contact, the grooves run in the same direction. On one or both surfaces of the elements, markings, numbers, letters, text or pattern elements may be found, for differentiating and determining the elements' positions.
