"Weblinear order is a binomial poset. To each binomial poset P we can associate a subalgebra R(P) of the incidence algebra of P: It consists of all functions f such that f(x,y) only depends on the length of the interval [x,y]. The algebra R(P) is isomorphic to an algebra of generating functions with the usual product of functions. " - Binomial generating function
