Abstract: Universal groups are subgroups of automorphism groups of right-angled buildings. Furthermore, they are totally disconnected locally compact topological groups and have interesting properties. I will present a finite presentation for discrete universal groups and results concerning the uniqueness of universal groups. Further, we will discuss the question of automatic continuity for universal groups. In particular, I will present conditions ensuring the continuity of abstract group homomorphisms into universal groups.
