Let r, n be integers, -n < r < n. An n x n matrix A is called r-indecomposable if it contains no k x I zero submatrix with k + ! = n -r + 1. If A is primitive, then there is a smallest positive integer, h~.(A), such that A'" is r-indecomposable for all m >1 hi'.(A). The integer h,: (A) is called the
