  • Once again the CMSC annual retreat was a huge success. We returned to Swanleigh and this year there were 21 attendees. This included Dugald McPherson who was visiting us at the time. An addition to the usual program of problem sessions, we had two lectures given by Simon Smith on infinite permutation groups. A special note of thanks should be given to Alice Devillers and Michael Giudici for the organisation.
