Starting from known results about the number of possible values for the permanents of (0, 1)-circulant matrices with three nonzero entries per row, and whose dimension n is prime, we prove corresponding results for n power of a prime, n product of two distinct primes, and n = 2 • 3 h .

In this paper we investigate the values of permanents according to the positions of zeros over m × n matrices with k zeros. We determine the maximum and minimum values of the permanent function and find the matrices which attain these extreme values.
