The breaking of SO(10) to SU (3)C × U (1)EM can be accomplished by just four Higgs fields: the symmetric rank-two tensor, S (54); a pair of spinors, C (16) and over(C, ̄) (over(16, -)); and a vector, T (10). This setup is also able to generate realistic fermion masses. The heavy color triplets in the vector and spinor fields mediate proton decay via dimension-five operators. The experimental bounds on proton decay constrain the structure and size of the Yukawa operators.
