Abstract
Explicit forms of Poincare generators corresponding to lightlike irreducible unitary representations are discussed and connected. Using the Coester transformation, we obtain new forms of the generators in the lightlike countinuous-spin case showing a manifestly helicity character. These new forms and other well-known ones are related through unitary transformations (rotations in spin space) and are discussed in connection with the discrete-spin case.
