Trinity's many college societies include the Trinity Mathematical Society, the oldest mathematical university society in the United Kingdom, and the First and Third Trinity Boat Club, its rowing club, which gives its name to the May Ball. Along with Christ's, Jesus, King's and St John's colleges, it has provided several well-known members of the Cambridge Apostles, an intellectual secret society. In 1848, Trinity hosted a meeting at which Cambridge undergraduates representing fee-paying private schools codified a set of early rules of football known as the Cambridge rules. Trinity's sister college is Christ Church, Oxford. Trinity has been linked with Westminster School since the school's re-foundation in 1560, and its Master is an ex officio governor of the school.
