CI-groups for ternary structures

Combinatorics 2026-02-10 v1

Abstract

We explicitly determine all CI-groups with respect to ternary relational structures that have the form C×DC \times D, where CC is cyclic and DD is either a dicyclic group whose order is not divisible by 33 or a dihedral group. Such groups are also CI-groups with respect to graphs and digraphs.
