Combinatorics Study Group

The Combinatorics Study Group seminar is held from 4pm-5pm (unless otherwise stated) on Fridays, in room W316 of the Queen's building at Queen Mary, University of London. We meet for tea before the seminar from 3.30pm in the Senior Common Room of the Queens building. (The Queen's building is on Mile End road midway between Stepney Green and Mile End Underground Stations. For more information, see the directions here). All the seminar attendees are cordially invited to join the speaker for drinks after the seminar, in the bar in the Queens building.
