  This is a transcript of a lecture course on Infinite Permutation Groups given
by Peter M. Neumann (1940-2020) in Oxford during the academic year 1988-1989.
The field of Infinite Permutation Groups only emerged as an independent field
of study in the 1980's. Most of the results described in these notes were at
the time of the lectures brand new and had either just recently appeared in
print or had not appeared formally. A large part of the results described is
either due to Peter himself or heavily influenced by him. These notes offer
Peter's personal take on a field that he was instrumental in creating and in
many cases ideas and questions that can not be found in the published
literature.
