چکیده
Let G be a solvable block transitive automorphism group of a 2− (v; 5; 1) design and suppose that G is not 0ag transitive. We will prove that (1) if G is point imprimitive, then v = 21, and G6 Z21 : Z6; (2) if G is point primitive, then G6A L(1; v) and v = p, where p is a prime number with p ≡ 21 (mod 40), and a an odd integer. c © 2002 Elsevier Science B.V.

This article is a contribution to the study of block-transitive automorphism groups of 2-(v, k, 1) block designs. Let D be a 2-(v, k, 1) design admitting a block-transitive, pointprimitive but not flag-transitive automorphism group G. Let kr = (k, v − 1) and q = p f for prime p. In this paper we prove that if G and D are as above and q > (3(krk − kr + 1)f) , then G does not admit a simple group...

Let G be a soluble block-transitive automorphism group of 2 − (v, 10, 1) design D. Then G is point-primitive and one of the following holds: (1)if 5 v, then v = pn and G ≤ AΓL(1, pn), where p = 2 is a prime and n a positive integer, and pn ≡ 1(mod90); (2) if 5 | v, then v = 5n, G ≤ AΓL(1, 5n), where n is a positive integer, and pn ≡ 1(mod18) Mathematics Subject Classification: 05B05, 20B25

In this paper we use Weil’s estimate on character sums to prove that large admissible prime powers q admit 2-(q, k, 1) designs having block-transitive automorphism groups in AGL(1, q).
متن کاملBlock Transitive 2 − ( v , 13 , 1 ) Designs and Classical Simple Groups
This article is a contribution to the study of the automorphism groups of 2−(v, k, 1) designs. Let D be 2−(v, 13, 1) design, G ≤ Aut(D) be block transitive, point primitive but not flag transitive. Then Soc(G), the socle of G, is not classical simple group over finite filed GF (q)(q odd). Mathematics Subject Classification: 05B05, 20B25
متن کاملFlag-transitive Point-primitive symmetric designs and three dimensional projective special linear groups
The main aim of this article is to study (v,k,λ)-symmetric designs admitting a flag-transitive and point-primitive automorphism group G whose socle is PSL(3,q). We indeed show that the only possible design satisfying these conditions is a Desarguesian projective plane PG(2,q) and G > PSL(3,q).
