Golden triangle (universities)
The golden triangle is the triangle formed by the university cities of Cambridge, London, and Oxford in the south east of England in the United Kingdom. The triangle is occasionally referred to as the Loxbridge triangle, a portmanteau of London and Oxbridge or, when limited to five members, the G5.
The list of universities considered to be members of the golden triangle varies between sources, but typically comprises the University of Cambridge, the University of Oxford, Imperial College London, King's College London, the London School of Economics and University College London. Some sources omit either or both of King's College London and the London School of Economics. while occasionally other universities are included, e.g. the London Business School and the London School of Hygiene and Tropical Medicine, or all of the higher education institutions in the three cities.
