> the 20 odd accommodation halls > the other 200 odd people in the hall For anyone unfamiliar with this somewhat uncommon usage, Matt is not saying that these are odd accommodation halls or odd people (strange or unusual). The "odd" here means that the preceding number is approximate - there are about 200 people in this hall, and about 20 halls in total. It's usually written with a hyphen to make this more clear: "the 20-odd accommodation halls" or "the other 200-odd people in the hall."
