Abstract
In this paper, the contragredient equivalence is extended to several matric es and a reduced form of the cyclically multiplicable n-tuples of matrices under this equivalence is defined and constructed. An invariant set of elem entary divisors (the spectrum of divisors) is found. This set describes com pletely the reduced form of a given cyclically multiplicable n-tuple.
