Symmetric (36,15,6) Design Having U(3,3) as an Automorphism Group
نویسنده
چکیده
Up to isomorphism there are four symmetric (36,15,6) designs with automorphisms of order 7. Full automorphism group of one of them is the Chevalley group G(2, 2) ~ U(3,3) : Z2 of order 12096. Unitary group U(3,3) acts transitively on that design.

Automorphism Group of a Possible 2-(121, 16, 2) Symmetric Design
Let D be a symmetric 2-(121, 16, 2) design with the automorphism group of Aut(D). In this paper the order of automorphism of prime order of Aut(D) is studied, and some results are obtained about the number of fixed points of these automorphisms. Also we will show that |Aut(D)|=2p 3q 5r 7s 11t 13u, where p, q, r, s, t and u are non-negative integers such that r, s, t, u ? 1. In addition we prese...
متن کاملFlag-transitive point-primitive $(v,k,4)$ symmetric designs with exceptional socle of Lie type
Let $G$ be an automorphism group of a $2$-$(v,k,4)$ symmetric design $mathcal D$. In this paper, we prove that if $G$ is flag-transitive point-primitive, then the socle of $G$ cannot be an exceptional group of Lie type.
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).

The construction of eight nonisomorphic new symmetric (100,45,20)-designs, having E25 . S3 as their full automorphism group, is presented. 1. PRELIMINARIES Symmetric (100,45,20)-designs belong to Menon series consisting of all symmetric designs with parameters (4t2, 2t2 t, t2 t). The existence of such a design, on the basis of its equivalence with the existence of regular Hadamard matrix of ord...
متن کاملAutomorphism Groups of Designs*
From a geometric point of view, the most interesting designs (see w 2 for definitions) are generally those admitting fairly large automorphism groups. The methods of finite permutat ion groups may be applied to such designs, and vice versa, as in [5, 6, 8, 11, 13 and 143. We shall prove several general results which are useful in the study of automorphism groups of designs, and then use some of...
