Wilson type groups are the first known examples of hereditarily just infinite (h.j.i.) profinite groups which are not virtually pro-p. In this talk I will firstly present a short survey on just infinite groups and where h.j.i. groups appeared. Secondly I will present the construction of Wilson type groups via iterated wreath products and finally I will discuss results obtained in my PhD regarding the Hausdorff dimension and the subgroup growth of these groups.
