Abstract

If D is a 2-(v, k, 1) design admitting a group G of automorphisms which acts doubly homogeneously but not doubly transitively on the points, we prove that v = pⁿ for some prime p ≡ 3 (mod 4), n is odd and
1. (1)D is an affine space over a subfield of GF(pⁿ) or

2. (2)D is a Netto system, k = 3 and p ≡ 7 (mod 12).
