A generalization of Fubini’s numbers. (English) Zbl 0698.05009

Summary: Starting from the classification method employed by D. Bushaw in D. Bushaw [SIAM Rev. 11, 214-225 (1969; Zbl 0175.097)] the problem of determining the number of non-equivalent positions obtained from a propositional function by quantification of the variables is studied.
