  A broader perspective is suggested for the study of higher dimensional
cosmological models. [1986: Considerations involving the Einstein constraints
and the Ricci form of the evolution equations for spatially homogeneous
spacetimes in 4 or more dimensions in the Taub time gauge (constant densitized
lapse) are used to show how many of the special exact solutions found at random
fit together into a larger picture in which the Taub spacetime solution plays
an instructive role. Concludes with some remarks on chaos.]
