We show that these methods are equivalent and are determined combinatorially by an inductive formula first given in a very special setting in [16]. Applications to de Rham theory and Massey products are given.}, number={2}, journal={MATHEMATICA SCANDINAVICA}, author={Johansson, Leif and Lambe, Larry}, year={2001}, month={Dec.}, pages={181–200} }
