%X The relativistic structure of the 143, 364, 572, 4212, and 5940 Ũ (12) multiplets is exhibited in the conventional wave formulation of quantum fields. Expressions for free Lagrangians, free propagators and interaction Lagrangians are given for S-matrix calculations. These last multiplets (4212, 5940) include spin 2 particles for which experimental evidence has recently been accumulating.
