Pseudocyclic and non-amorphic fusion schemes of the cyclotomic association schemes


الملخص بالإنكليزية

We construct twelve infinite families of pseudocyclic and non-amorphic association schemes, in which each nontrivial relation is a strongly regular graph. Three of the twelve families generalize the counterexamples to A. V. Ivanovs conjecture by Ikuta and Munemasa [15].
