On a conjecture concerning the fraction of invertible m-times persymmetric matrices over F_2
In this paper we state that the fraction of invertible m-times persymmetric matrices over F_2 is equal to \prod_{j=1}^{m}(1-2^{-j})

Exponential sums and rank of triple persymmetric matrices over F_2
We obtain using exponential quadratic sums, explicit expressions for the number of triple persymmetric matrices over F_2 of given rank. (A matrix [a(i,j)] is persymmetric if a(i,j) = a(r,s) for i+j = r+s)
