The work considers an equivalence relation in the set of all n × m matrices with entries in the set [p] = {0, 1, … p − 1}. In each element of the factor-set generated by this relation, we define the concept of canonical matrix, namely the minimal element with respect to the lexicographic order. We have found a necessary and sufficient condition for an arbitrary matrix with entries in the set  [p] to be canonical. For this purpose, the matrices are uniquely represented by ordered n-tuples of integers.
