How feasible is it to prove Kazhdan's property (T) by a computer?
Why in particular $\mathrm{Aut}(F_4)$? is the answer known for $\mathrm{Aut}(F_2)$ and $\mathrm{Aut}(F_3)$?

Geometric characterization of property (T) and the Haagerup property
@YvesCornulier: could you please direct me to the reference showing that property (T) is not QI-invariant? Thanks!
