We study topological defects arising in the Grand Unification Model SU(6)L ⊗SU(6)c⊗SU(6)R ×Z3. In particular we show the existence of massive magnetic monopoles, cosmic strings and global textures in a particular symmetry breaking chain. We comment on the possible relation to astrophysical problems, in particular to the explanation of the origin of the highest energy cosmic rays reported recent...
