Horváth Erzsébet: Remarks on a method constructing arbitrary even depth

Abstract:
This is a joint work with H. A. Janabi and T. Breuer.
In 2011 Lars Kadison posed the problem if there are subgroups of even depth 2n for n>6.
We overview some steps leading to the solution of this problem and we also consider related questions.
