  This is a sequel to our paper arXiv:1402.2546 to appear in the Journal of
Geometric Analysis in which we concentrate on developing some of the
topological properties of Sasaki-Einstein manifolds. In particular, we
explicitly compute the cohomology rings for several cases not treated in
arXiv:1402.2546 and give a formula for homotopy equivalence in one particular
7-dimensional case.
