This collection mostly covers Dixon's Bob Minor; other similar rule-based constructions may be included, but they are often tedious to represent in terms of methods as currently defined. For a good overview see https://www.cantabgold.net/users/pje24/dixonoids.html. For more on the history of Dixon's see the 4-part article by John Eisel commencing in https://bb.ringingworld.co.uk/issues/5734 (19 March 2021).
