Abstract
We introduce the method of assigning values in a ring to the points of a t-design. We give the notion of an \(\left[ {A,t} \right]\)-design. We give a generalization of the concept of association scheme, and obtain a method to construct some of them from t-designs that generalizes the well-known construction for the case of ordinary association schemes.
