Reduced twisted group C*-algebras of groups with property P_PHP are completely selfless, and those of finite-by-G extensions have stable rank one and are pure.
Certain crossed products of C(X,D) by minimal homeomorphisms and compact group actions with Rokhlin-type properties are pure C*-algebras with stable rank one.
Factorial tracially complete C*-algebras with CPoU have real rank zero and stable rank one, giving a description of the Cuntz semigroup including for Z-stable cases.
Reduced twisted group C*-algebras of selfless groups with rapid decay are selfless, implying that those of acylindrically hyperbolic groups with rapid decay are pure and have strict comparison.
