报告摘要：Steiner and Kirkman triple systems (KTSs) are among the most popular combinatorial designs and their existence has been settled a long time ago. Yet, there are various open questions on the existence of triple systems having, in addition, a well-behaved automorphism group. 

In this talk, we will survey some recent constructive methods [1, 2, 3] that allowed us to build Steiner and Kirkman triple systems having an automorphism group that fixes $f$ points and acts sharply transitively on the remaining.
