Outer automorphism group of Brieskorn homology sphere?
@DannyRubeman Thanks so much! If I may "go to your well" one more tome, do you have a reference for that?

Aspherical manifold with superperfect fundamental group and non-trivial center?
Indeed, the book by Saveliev also explicitly includes the generator ℎ of the center as one of the generators of the fundamental group; thanks so much for the response

Aspherical manifold with superperfect fundamental group and non-trivial center?
I got the book today, and it answered all my questions and more; I'll post an "answer" and my exciting MATLAB .m script to compute the Bézout coefficients corresponding to the relatively prime integers in the Brieskorn homology sphere tomorrow

Aspherical manifold with superperfect fundamental group and non-trivial center?
I also need to know a product of generators representing a generator of the center; I can't edit the above

Aspherical manifold with superperfect fundamental group and non-trivial center?
I was and am planning on collecting the above in an answer, but was waiting for the book smile.amazon.com/Invariants-Homology-3-Spheres-Nikolai-Savel‌​iev/… to come in at the library to make sure I have all I need for the presentation of the fundamental group and handlebody decomposition of the minimal Brieskorn homology sphere to meet my criteria; sorry if I dragged my feet posting this

Aspherical manifold with superperfect fundamental group and non-trivial center?
@DannyRuberman Wow, that's awesome, thank you! I'm actually going to take a fiber bundle with a torus as the base manifold and need the total space to be at least 6-dim'l at some point, so I could just use a 3-dim'l torus or a 2-dim'l torus and a higher-dim'l example of what you just suggested; it's kind-of "six of one, half a dozen of another" to me at this point. However, modulo the dimension of the manifold, this is exactly what I needed, so thank you
