ON 4-EQUIVALENCED ASSOCIATION SCHEMES
PARK, JEONG RYE;

Abstract
Let ($\small{{\Omega}}$, S) be an association scheme where $\small{{\Omega}}$ is a non-empty finite set and S is a partition of $\small{{\Omega}{\times}{\Omega}}$. For a positive integer k we say that ($\small{{\Omega}}$, S) is k-equivalenced if each non-diagonal element of S has valency k. In this paper we focus on 4-equivalenced association schemes, and prove that they are transitive.
