The (56, 11, 2) design of Hall, Lane, and Wales
1973
Journal of combinatorial theory. Series A
In Hall, Lane, and Wales [3] , two classes of symmetric designs are constructed from rank three permutation groups (see [3] and [4] for definitions and notation). As an example of one of these constructions, they exhibit a symmetric design D with the parameters (56, 11, 2) , that is to say, with 56 points, 56 blocks, 11 points per block and any 2 distinct points determine exactly 2 blocks. The rank three representation of PSL(3, 4) of degree 56 is used in the construction. This design can be
