PRIMITIVE SYMMETRIC DESIGNS HAVING UP TO 2500 POINTS
We present the construction of primitive (v , k , lambda) symmetric designs with v < 2500. Up to a few unsolved cases, the total of 116 designs is obtained and their full automorphism groups are analyzed. The method of construction is based on a design automorphism group (primitive) action. In the case of affine type primitive groups and v = p^m, p prime and m > 1, 60 designs are obtained ; non-existence results include the theory of difference sets and multiplier theorems in particular ([1]). The rest of 56 obtained designs have primitive automorphism groups of almost simple or product type. The research involves programming and wide-range computations. We make use of software package GAP and the library of primitive groups which it contains. References [1] S. Braić, A. Golemac, J. Mandić and T.
