-<​blockquote>​The little group is a subgroup of the Poincare 
-group which leaves the four-momentum of a 
-given particle invariant. The little groups for 
-massive and massless particles are locally 
-isomorphic to the three-dimensional rotation 
-group and the two-dimensional euclidean group 
-respectively. <​cite>​GAUGE TRANSFORMATIONS AS LORENTZ-BOOSTED ROTATIONS by D. HAN et. al.</​cite></​blockquote>​
