Abstract

Using primitive actions of the projective special linear groups PSL2(q), q = 37, 41, 43, 47 and 49 some 1-designs are constructed. The automorphism group of all the constructed designs are found. It is shown that all subgroups of the automorphism group of PSL2(q), q = 37, 41, 43, 47 and 49 appear as the automorphism group of the constructed designs.
