Özet
The algebra of O(3, 3) is contracted to that of E(2)-like groups in the infinite-momentum limit. It is shown through this process that there are 18 different possibilities for the representations of E(2)-like algebra if they are to be expressed in terms of Dirac gamma-matrices. It is also pointed out that the generators of this algebra are independent of the particular representation of the gamma-matrices. Possible implications of this analysis is discussed.
