Embedding the Cremmer-Scherk Configuration into SO(16) and Effective SO(10) Gauge Symmetry

We show the explicit embedding of the Cremmer-Scherk configuration into SO(16) Gauge theory and that the non-Abelian flux breaks the gauge symmetry SO(16) to SO(10). Adjoint scalar fields of SO(10) coming from components of six compact directions become massive. There are several scalar fields beloging to the representation 10, which may break SO(10).
