For a nite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable sub-division. In this paper we construct minimal models of the k-fold generalised multiplications of circles in the category of relational structures, including poset models. In particular, we obtain higher dimensional analogues of a cer-tain ternary multiplication of crownsenOpen Access.
