Arasu, K.T. and A. Pott, Cyclic affine planes and Paley difference sets, Discrete Mathematics 106/107 (1992) 19-23. The existence of a cyclic affine plane implies the existence of a Paley type difference set. We use the existence of this difference set to give the following condition on the existence of cyclic affine planes of order n: If n 8 mod 16 then n 1 must be a prime. We discuss the stru...
