Drivers are defined in an article in
Mathematics of Computation in 1975 by Richard K Guy and John Selfridge. You can find the article free of charge
here. There is a later article clarifying the proof. That one is available
here.
(Thanks to the American Mathematical Society who has made its older articles available free of change.)
