We discuss a recently proposed SO(10)v×SO(10)H grand unified-extended technicolour model. Because proton decay is probably too fast in this model, we study the other possible models based on SO(10)v×SO(10)H. As a result of this analysis only a few of these models could possibly be realistic, they would be slight modifications of that previously proposed. None of them predicts the expected value for ΛTC, it must be adjusted by introducing another mass scale. In these models ordinary fermion masses tend to be too small. © 1982 Springer-Verlag.
