If you combine three spin- particles, you can get a total spin of 3/2 or 1/2 (and the latter can be achieved in two distinct ways). Construct the quadruplet and the two doublets, using the notation of Equations 4.175 and 4.176:

Take it from there make sure |1/2 1/2)₂ is orthogonal to |1/2 1/2)₁ and to | 3/2 1/2).
