This dataset is a collection of sequences of sets. The sets are constructed from interactions recorded by wearable sensors in a primary school. The sensors record proximity-based contacts every 20 seconds. There is one sequence of sets per person, and we consider the set of individuals that a person comes into contact within each 20 second interval to be a set (only nonempty sets are considered; some intervals contain no interactions). All sequences contain at least 10 sets, and only sets of size at most 5 are considered. Some basic statistics of this dataset are:

• number of sequences: 242
• number of unique elements appearing in sets: 242
• number of sets: 174,796
• number of unique sets: 18,412
