A collection formula

A table of partially ordered sets, corresponding to the basis commutators (in Hall's sense) of weight 9, is given. On the basis of this table, the exponents in the collection formula can be found by elementary combinatorial methods. An example is given.Translated from Zapiski Nauchnykh Seminarov Leningardskogo Otdeleniya Matematicheskogo Instituta im. V. A. Steklova AN SSSR, Vol. 46, pp. 59–63, 1974.
