摘要
The simple incidence structure D(A,2), formed by the points and the unordered pairs of distinct parallel lines of a finite affine plane A = (P, L) of order n > 4, is a 2-(n(2), 2n, 2n - 1) design with intersection numbers 0, 4, n. In this paper, we show that the converse is true, When n >= 5 is an odd integer.
