Abstract :
In this paper, the type-II matrices on (negative) Latin square graphs are considered and
it is proved that, under certain conditions, the Nomura algebras of such type-II matrices are trivial.
In addition, we construct type-II matrices on doubly regular tournaments and show that the Nomura
algebras of such matrices are also trivial.
