Abstract
We show that Galois theory of cyclotomic number fields provides a powe rful tool to construct systematically integer-valued matrices commutin g with the modular matrix S, as well as automorphisms of the fusion ru les. Both of these prescriptions allow the construction of modular inv ariants and offer new insight in the structure of known exceptional in variants.
