Heden, O., On the modular n-queen problem, Discrete Mathematics 102 (1992) 155-161. Let M(n) denote the maximum number of queens on a modular chessboard such that no two attack each other. We prove that if 4 or 6 divides n then M(n) c n -2 and if gcd(n, 24) = 8 then M(n) 2 n -2. We also show that M

We prove that if q + 1 E 8 or 16 (mod 24) then, for any integer n in the interval (q2 + 1)/2 + 3 < n < (Sq' + 4q + 7)/8, there is a maximal partial spread of size n in PG(3, q).
