In this paper, we consider cyclotomic association schemes. We focus on the adjacency algebra ofSover algebraically closed fieldsKof characteristicp. If,, or, we identify the adjacency algebra ofSoverKas a quotient of a polynomial ring over an admissible ideal. In several cases, we determine the indecomposable direct sum decomposition of the standard module ofS. As a consequence, we are able to compute thep-rank of several specific elements of the adjacency algebra ofSoverK.
